Can Motivation Normalize Working Memory and Task Persistence in Children with Attention-Deficit/Hyperactivity Disorder? The Effects of Money and Computer-Gaming

Visual-spatial Working Memory (WM) is the most impaired executive function in children with Attention-Deficit/Hyperactivity Disorder (ADHD). Some suggest that deficits in executive functioning are caused by motivational deficits. However, there are no studies that investigate the effects of motivation on the visual-spatial WM of children with- and without ADHD. Studies examining this in executive functions other than WM, show inconsistent results. These inconsistencies may be related to differences in the reinforcement used. The effects of different reinforcers on WM performance were investigated in 30 children with ADHD and 31 non-ADHD controls. A visual-spatial WM task was administered in four reinforcement conditions: Feedback-only, 1 euro, 10 euros, and a computer-game version of the task. In the Feedback-only condition, children with ADHD performed worse on the WM measure than controls. Although incentives significantly improved the WM performance of children with ADHD, even the strongest incentives (10 euros and Gaming) were unable to normalize their performance. Feedback-only provided sufficient reinforcement for controls to reach optimal performance, while children with ADHD required extra reinforcement. Only children with ADHD showed a decrease in performance over time. Importantly, the strongest incentives (10 euros and Gaming) normalized persistence of performance in these children, whereas 1 euro had no such effect. Both executive and motivational deficits give rise to visual-spatial WM deficits in ADHD. Problems with task-persistence in ADHD result from motivational deficits. In ADHD-reinforcement studies and clinical practice (e.g., assessment), reinforcement intensity can be a confounding factor and should be taken into account. Gaming can be a cost-effective way to maximize performance in ADHD.     

An examination of vicarious reinforcement processes in children

The primary purpose of the present investigation was to examine vicarious reinforcement processes in children. More specifically, the effects on one child of observing another same-sex child receive direct reinforcement were explored across three different age levels. Subjects were 216 children, randomly assigned to experimental or control conditions. For the control condition, neither child in the same-sex, same-age dyad received reinforcement for performance on the experimental task. For the experimental condition, one child in each dyad received direct social reinforcement for performance, while the other child received no social reinforcement for similar performance. Although children who observed other children receive direct social reinforcement initially increased performance (as predicted by vicarious reinforcement hypotheses), their performance soon decreased and was characterized by verbal and nonverbal responses which appeared to interfere with task performance (e.g., “Hey, I can do them too”, “Look at mine”, “There's no use in trying”). It appeared as if these observing children were being punished for their performance. Such effects were more pronounced for older than younger children; however, they were observed equally in boys and girls. Results were discussed in terms of vicarious reinforcement and “implicit punishment” hypotheses. Implications for applied settings were also addressed.     

A critical eye: Praise directed toward traits increases children’s eye fixations on errors and decreases motivation

Although there is evidence that praise of different types (i.e., generic vs. nongeneric) influences motivation, it is unclear how this occurs. Generic praise (e.g., ??You are smart??) conveys that a child possesses a trait responsible for their performance, whereas nongeneric praise (e.g., ??You worked hard??) conveys that performance is effort-based. Because praise conveys the basis for success, praise may change the interpretation and salience of errors. Specifically, generic praise may highlight the threatening nature of error (i.e., the child does not possess this trait). Because attention is drawn to threats in the environment, we expected generic praise to increase attention to error. We used eyetracking to measure implicit responses to errors (i.e., visual attention: fixation counts and durations) in order to determine the relation between visual attention and verbal reports of motivation (persistence and self-evaluations) in 30 four- to seven-year-old children. Children first saw pictures attributed to them, for which they received either generic or nongeneric praise. The children then saw pictures attributed to them that contained errors??that is, missing features. As a pretest and posttest, the children saw pictures that were ??drawn by other children,?? half of which contained errors. The results indicated that children who received generic praise (??you are a good drawer??) produced more and longer fixations on errors, both their ??own?? and on ??other children??s,?? than did children who received nongeneric praise (??you did a good job drawing??). More fixations on errors were related to lower persistence and lower self-evaluations. These results suggest that generic praise increases attention to errors because error threatens the possession of a positive trait.     

Differential effects of social and non‐social reward on response inhibition in children and adolescents

An important issue in the field of clinical and developmental psychopathology is whether cognitive control processes, such as response inhibition, can be specifically enhanced by motivation. To determine whether non‐social (i.e. monetary) and social (i.e. positive facial expressions) rewards are able to differentially improve response inhibition accuracy in typically developing children and adolescents, an ‘incentive’ go/no‐go task was applied with reward contingencies for successful inhibition. In addition, the impact of children's personality traits (such as reward seeking and empathy) on monetary and social reward responsiveness was assessed in 65 boys, ages 8 to 12 years. All subjects were tested twice: At baseline, inhibitory control was assessed without reward, and then subjects were pseudorandomly assigned to one of four experimental conditions, including (1) social reward only, (2) monetary reward only, (3) mixed social and monetary reward, or (4) a retest condition without reward. Both social and non‐social reward significantly improved task performance, although larger effects were observed for monetary reward. The higher the children scored on reward seeking scales, the larger was their improvement in response inhibition, but only if monetary reward was used. In addition, there was a tendency for an association between empathic skills and benefits from social reward. These data suggest that social incentives do not have an equally strong reinforcing value as compared to financial incentives. However, different personality traits seem to determine to what extent a child profits from different types of reward. Clinical implications regarding probable hyposensitivity to social reward in subjects with autism and dysregulated reward‐seeking behaviour in children with attention‐deficit/hyperactivity disorder (ADHD) are discussed.     

Teacher and peer reactions to boys' and girls' play styles

Seventy children (35 boys and 35 girls) aged 24 to 30 months were observed in play groups consisting of 12–15 2- and 3-year-old children and two teachers. The social interaction was coded using an observation schedule which allowed for coding the children's behaviors and reactions to that behavior by others in the environment. The behavior scores were factor analyzed, using the complete sample of 180 children with six factors (play styles) resulting. Children who were high and low on each factor were examined to see if play style influenced the type of social reaction received. Children who preferred to work at tasks quietly received positive teacher feedback, but there was no change in peer interaction; children who engaged in active motor play received positive peer feedback, but negative teacher reactions. Children who were passive received less peer reaction and played alone significantly more than other children. Sex differences in reactions did not appear except when the child was engaged in male- and female-typical behaviors when examining scores on one factor only. When combinations of factors are examined (e.g., activity level and task performance), then different patterns of responses start to appear for boys and girls. The implications for differing patterns of social reactions to different play styles are discussed.Data analyses were supported by BRSG Grant RR07980 awarded by the Biomedical Research Support Grant Program, Division of Research Resources, National Institutes of Health. The final write-up was completed on a postdoctoral fellowship (Grant No. 1 T32 MH 16955-01) through the Oregon Social Learning Center.     

The Effects of Feedback on Perseverative Errors in Preschool Aged Children

Research using the Dimensional Change Card Sort (DCCS) showed that young children are usually able to sort accurately by an initial rule but are unable to switch to a new rule when the two rules conflict. In 2 experiments, the DCCS was modified to study the effects of feedback on 3- to 5-year-old children in a problem-solving task. In Experiment 1, half of the children in each of two age groups (36 to 44 months and 52 to 60 months) were administered the DCCS task using the standard (no feedback) procedure and the other half received feedback on their post-switch responses. Children who received feedback were able to categorize according to the new (correct) rule, whereas the children in the younger age group who did not receive feedback continued to perseverate. Experiment 2 with 3-year-olds replicated the results from Experiment 1 but found that children's successful performance with feedback on the card-sorting task did not lead to improved performance on the post-switch phase of a subsequent DCCS task. Successful performance under conditions of feedback in both studies implies that 3-year-olds are capable of shifting their response mode from one rule to an alternate rule under conditions that offer clear guidance. Poor performance on the standard version is interpreted to be a reflection of the inability to monitor their own task performance in the absence of clear contextual cues.     

Comparing Attention to Socially-Relevant Stimuli in Autism Spectrum Disorder and Developmental Coordination Disorder

Difficulties with social interaction have been reported in both children with an autism spectrum disorder (ASD) and children with developmental coordination disorder (DCD), although these disorders have very different diagnostic characteristics. To date, assessment of social skills in a DCD population has been limited to paper-based assessment or parent report. The present study employed eye tracking methodology to examine how children attend to socially-relevant stimuli, comparing 28 children with DCD, 28 children with ASD and 26 typically-developing (TD) age-matched controls (aged 7–10). Eye movements were recorded while children viewed 30 images, half of which were classed as ‘Individual’ (one person in the scene, direct gaze) and the other half were ‘Social’ (more naturalistic scenes showing an interaction). Children with ASD spent significantly less time looking at the face/eye regions in the images than TD children, but children with DCD performed between the ASD and TD groups in this respect. Children with DCD demonstrated a reduced tendency to follow gaze, in comparison to the ASD group. Our findings confirm that social atypicalities are present in both ASD and to a lesser extent DCD, but follow a different pattern. Future research would benefit from considering the developmental nature of the observed findings and their implications for support.     

SOCIAL SKILLS TRAINING WITH CHILDREN: PROCEED WITH CAUTION

Three learning disabled children, selected on the basis of peer sociometric ratings and teacher referral, received social skills training. A group training procedure consisting of coaching, modeling, behavior rehearsal, and feedback was used to teach children the target behaviors of eye contact and appropriate verbal responses. A multiple baseline analysis across target behaviors was used to demonstrate treatment effectiveness on role-play scenes trained during treatment sessions. Duration of speech was measured as an untrained, corollary measure. The following measures were also obtained during baseline, posttreatment, and 1-mo follow-up for the experimental subjects and three control subjects: (a) performance on role-play scenes not trained during treatment sessions; (b) behavioral observations in a free play setting, and (c) sociometric ratings. In addition, the trained and untrained role-play scenes were administered by novel experimenters following treatment. The results indicated that socially unskilled, learning disabled children can be taught to respond appropriately to role-play situations. However, improved performance did not generalize to the natural school setting and treatment did not effect ratings of peer acceptance. The implications of these findings for future social skills training with children are discussed.     

Pandora's box reopened? The assessment of social skills

Social skills are viewed as an organizing principle for relating a variety of superficially dissimilar behaviors under a single megaconstruct. The underlying theme of this article is that since social skills are a megaconstruct we must be constantly vigilant lest we begin to regard them as a static, invariant dispositional-trait-like unit. Within this context, various theoretical-definitional issues are discussed and reduction of these issues is urged for any particular assessment task if adequate assessment is to be achieved. Social skills are viewed as response capabilities inferred from performance. Since performance is influenced by other parameters (e.g., cognitive factors — emotional states), these other parameters may need to be measured depending on the assessment task. The advantages and disadvantages of both molar unit and molecular unit recording of social skills are discussed. It is concluded that neither type of unit should be regarded as the proper measurement unit. The proper unit size is an empirical question which may differ as a function of the assessment task. An analogy is provided regarding the assessment of the megaconstruct of intelligence. It is hoped that we can profit from an examination of the strategies employed in intellectual assessment. Behavior assessors are urged to refamiliarize themselves with various psychometric theories and strategies to increase their methodological sophistication with respect to the assessment of social skills.     

Psychometric Properties of a Social Skills Assessment using a Virtual Environment

Social Anxiety Disorder (SAD) is a marked and persistent fear of social and/or performance situations in which embarrassment or scrutiny from others may occur. One form of behavioral assessment is a Role Play Task (RPT). However, RPTs often are not feasible in clinical settings due to the common obstacles in implementation. Thus, the current study examines the feasibility, acceptability and psychometric properties of a virtual environment based social skills assessment compared to the traditional RPT. Forty-six children, ages 7 to 14, participated in two assessment conditions: RPT and a virtual environment behavioral assessment (VE BAT). Participants reported self-ratings of anxiety and acceptability, while blinded observers rated social skills and overall social anxiety. An ANCOVA, covarying for age, revealed (a) no significant task difference for voice volume, speech latency, number of words spoken, effectiveness, and SAM ratings; (b) that the VE BAT was more feasible to implement in terms of personnel time and costs and; (c) more overall anxiety during the RPT task than during the VE BAT task. In addition, the VE BAT demonstrated moderate concurrent validity when correlating the self-report ratings of anxiety with the Social Phobia and Anxiety Inventory for Children (SPAI-C). The current study addresses many of the impediments to conducting RPTs in a clinical setting and, overall, supports the utilization of VE BATS as a viable alternative for the behavioral assessment of social skills in children. Further implications address the potential for the armamentarium for social skills training with children with SAD.     

Background and Focal Environmental Conditions of the Home and Attention in Young Children1

A conceptual distinction is drawn between two aspects of the perceptual field, focal features which the individual selectively engages and extraneous background conditions which serve as a context within which these activities occur, and a study is described which examined the relationship between these aspects of the home environment and attentional skills in young children. Ninety-four families with kindergarten age children participated in the project. Interviews and observations were conducted in the homes in order to assess background conditions (e.g., noise and activity levels) and variation and patterning of focal features (e.g., furnishings), and tasks designed to assess attentional skills were administered to the children. The results indicated that children from homes with high noise levels had longer response latencies on a visual search task and also subsequently recognized fewer incidental aspects of the task than did children from quieter homes. Furthermore, the former group appeared to be less distractible, i.e., less responsive to an auditory distractor. Neither variation nor patterning of focal features was found to be associated with task performance. In general, the findings are interpreted as indicating the adverse effects of high noise levels in the home on attentional skills in spite of apparent adaptation, i.e., lower distractibility, to these conditions.     

External focus of attention improves performance in a speeded aiming task

Athletic skills are often executed better when learners focus attention externally (e.g., on the trajectory of the ball after a tennis serve), rather than internally (e.g., on the position of their arm) (e.g., Wulf, 2007a). The current study explored the effects of attention focus on learning of speeded responses, and examined whether these benefits hold for retention and transfer. Participants performed a computerized speeded aiming task while focusing on the direction of the cursor (external focus) versus the direction in which their hand moved the mouse (internal focus). One week later, half of the participants performed the same task again (retention), and half performed the task under conditions in which the mouse movements were changed (transfer). Relative to internal focus, external focus led to faster acquisition and better maintenance of speeded responses over the retention interval.     

Parent‐implemented behavioral skills training of social skills

Impairment in social skills is a primary feature of Autism Spectrum Disorders (ASDs). Research indicates that social skills are intimately tied to social development and negative social consequences can persist if specific social behaviors are not acquired. The present study evaluated the effects of behavioral skills training (BST) on teaching four parents of children with ASDs to be social skills trainers. A nonconcurrent multiple baseline design across parent–child dyads was employed and direct observation was used to assess parent and child behaviors Results demonstrated substantial improvement in social skills teaching for all participants for trained and untrained skills. Ancillary measures of child performance indicated improvement in skills as well. High levels of correct teaching responses were maintained at a 1 month follow‐up. This study extends current literature on BST while also providing a helpful, low‐effort strategy to modify how parents can work with their children to improve their social skills.     

Emotion recognition in children with Fetal Alcohol Spectrum Disorders

There is a limited amount of research that examines social-emotional functioning in children with Fetal Alcohol Spectrum Disorder (FASD), and the majority of it relies on parent and teacher reports of social impairments. Because these provide broad measures of social function, they fail to elucidate the underlying specific skills with which this group of children has difficulty. The current study examines emotion-recognition abilities in children with FASD, as it plays a central role in social interaction. Participants were 22 children with diagnosed FASD (ages 8–14), and age- and gender-matched typically developing controls. Tasks included measures of emotion recognition from three nonlinguistic modalities: facial expressions, emotional tone of voice, and body positioning and movement. Participant’s parents completed measures of adaptive and behavioral function that were related to children’s performance on aspects of emotion recognition. Overall, the results show that children with FASD have more difficulties with emotion recognition than typically developing age-matched peers, but these difficulties may not be clinically significant (e.g., smaller effect size) or may be specific to the age of the individual exhibiting the emotion (i.e., child vs. adult). These results are discussed in the context of previous studies.     

The utility of math difficulties, internalized psychopathology, and visual-spatial deficits to identify children with the nonverbal learning disability syndrome: evidence for a visualspatial disability.

This study examined the criteria currently employed to identify children with the nonverbal learning disability syndrome (NVLD). The most widely accepted definition of NVLD relies on deficits in visual-spatial-organizational, tactile-perceptual, psychomotor, and nonverbal problem-solving skills. These deficits are believed to coexist with strengths in rote verbal learning, phoneme-grapheme matching, verbal output, and verbal classification. The combination of these assets and deficits has been hypothesized to lead to psychosocial and academic problems, including difficulties with mathematics and increased rates of psychopathology. This study compared performance of three groups of children: those with NVLD, those with verbal learning disabilities (VLD), and controls. The results show that the criteria currently employed to identify children with NVLD may not adequately differentiate them. In contrast to previous findings, the study reveals that children with NVLD can demonstrate good math abilities when performing certain types of math tasks, especially those that draw on their robust verbal skills. Also in contrast to most previous findings, in this study children with NVLD (and normal controls) demonstrated lower rates of psychopathology than children with VLD. Finally, for children with NVLD it appears that their visual-perceptual deficits may include a primary deficit in locating objects in space. Based in part on the findings of this study, it may be helpful for diagnostic and treatment purposes to reserve the term Nonverbal Learning Disability for children whose visual-spatial deficits are primary and severe enough to affect academic performance in subjects such as written mathematics. Given the integral nature of social relations in children's lives, a separate category (e.g., social processing disorder) could be created for children whose social skills deficits are primary and impair their social interactions. A broader nonverbal learning model or syndrome, as conceptualized by Rourke (1995), could be retained for describing a broader constellation of assets and deficits across disease types.     

A descriptive analysis of potential reinforcement contingencies in the preschool classroom

In recent years, functional analysis methods have been extended to classroom settings; however, research has not evaluated the extent to which consequences presented during functional analysis are associated with problem behavior under naturalistic classroom conditions. Therefore, the purpose of this study was to determine whether the social consequences commonly manipulated in functional analyses occur in typical preschool classrooms. A total of 14 children attending preschool programs participated in the study. Data were collected on the occurrence of antecedent events (e.g., presentation of tasks), child behaviors (e.g., aggression), and teacher responses (e.g., delivery of attention). The probability of various teacher responses given child behavior was then calculated and compared to the response-independent probabilities of teacher responses. Attention was found to be the most common classroom consequence (100% of children), followed by material presentation (79% of children), and escape from instructional tasks (33% of children). Comparisons of conditional and response-independent probabilities showed that the probability of teacher attention increased given the occurrence of problem behavior for all children, suggesting that a contingency existed between these two events. Results suggest that functional analyses that test the effects of attention, escape, and access to materials on problem behavior may be appropriate for preschool settings.     

Social phobia: individual response patterns and the effects of behavioral and cognitive interventions

In the present study, the role of individual response patterns in the treatment of social phobic patients was investigated. Seventy-four patients were diagnosed as social phobics. On the basis of extreme scores on a behavioral test (the Simulated Social Interaction Test) and on a cognitive measure (the Rational Behavior Inventory), the response patterns of 39 patients were analyzed, and the patients themselves were classified as either 'behavioral reactors' or 'cognitive reactors'. Half of the patients with each response pattern received a behavioral focused treatment, i.e. social skills training (SST), while the other half received a cognitive oriented treatment, i.e. rational emotive therapy (RET). Patients received group therapy in eight weekly sessions. Within-group differences showed a considerable improvement in all treatment groups. Between-group differences failed to lend support to the hypothesis that treatment that fits a response pattern (i.e. SST for behavioral reactors and RET for cognitive reactors) will result in a greater improvement than one that does not.     

Biographic and behavioral factors are associated with music-related motor skills in children pianists

This study aimed to identify biographical and behavioral factors associated with children pianists’ motor skills using an objective assessment of a music-relevant motor task. Motor skills at the piano were assessed in 30 children pianists by measuring temporal unevenness in standardized scale playing using musical instrument digital interface (MIDI)-based scale analysis. Questionnaires were used to collect detailed information about the amount of time playing the piano, practice characteristics, attitudes toward music and practice, and the environment of music and practice. Associations between performance values and variables from the questionnaire were investigated using multivariable linear regression. A higher number of years playing the piano, more frequent parental involvement in the child’s practice, more frequent practice of technical exercises, and greater enjoyment of practice and of the visual arts were associated with better motor performance. In addition to cumulative experience and aspects of practice, extrinsic motivational factors (e.g., parental interest) and intrinsic motivational factors (e.g., an artistic disposition) were associated with better performance on a musically-relevant motor task in children pianists.     

Independence training vs modeling procedures for teaching phone conversation skills to the mentally retarded

Forty-five mildly mentally retarded adults were assessed for deficits in telephone conversational skills. They were ranked on the basis of their pretest scores and matched into triplets on skill level. One member from each of these groups was then randomly assigned to either a no-treatment control group, a modeling condition or independence training—a treatment that incorporated social reinforcement, instructions, performance feedback, modeling, shaping by successive approximations and self-monitoring and evaluation. For the two latter conditions, treatment was provided three times weekly for 2 months in group sessions (N = 5) of 1 hr duration. The dependent variable, conversational skills of subjects was assessed at pretest, posttest and at a 3-month follow-up based on verbal responses that subjects made to nine questions asked by an experimenter and related social responses during a phone call. Independence training proved to be significantly more effective than the other two experimental conditions at posttest and follow-up. In addition, modeling proved to be significantly more effective than the no-treatment controls at both of these assessment points.     

Social Skills Differences among Attention-Deficit/Hyperactivity Disorder Types in a Chat Room Assessment Task

This study assessed social skills in 116 children aged 7-12 with ADHD-Combined Type (ADHD-C; n=33), ADHD-Inattentive Type (ADHD-I; n=45), and comparison children (n=38), with consideration of the role sluggish cognitive tempo (SCT) symptoms play in distinguishing profiles. Social skills were assessed using a novel computerized chat room task, in which participants were encouraged to join a conversation and type messages to interact with four computer-simulated peers. Every participant received the identical stimulus from the simulated peers, but was free to respond to it in his or her own unique way. Relative to comparison children, children with ADHD-C made off-topic and hostile responses; children with ADHD-I made off-topic responses, few responses and showed poor memory for the conversation. ADHD subtype differences remained after statistical control of IQ, reading achievement, typing skill, and comorbid disruptive behavior disorders. SCT symptoms, most prevalent among children with ADHD-I, predicted a distinct pattern of social withdrawal and lower hostility. Parent and teacher ratings and in-vivo observations of social skills correlate with this new measure.
