The development of perceived structure and attention: evidence from divided and selective attention tasks

Three experiments provide converging evidence for the view that both perceived structure and attention change during the elementary school years. Kindergarteners, second graders, and adults performed three speeded tasks: divided attention to conjunctions of features, selective attention to orthogonal dimensions and selective attention to correlated dimensions. The tasks were performed with sizes and shapes that were either spatially integrated or spatially separated. In the divided attention task, conjunctions were identified as quickly as single features with integrated stimuli at all ages, but conjunctions were identified more slowly than single features with separated stimuli by all age group. In the orthogonal dimensions task, interference was observed with integrated stimuli across ages, but the interference in adult performance was asymmetric. With separated stimuli, interference was gradually eliminated with increasing age. In correlated dimensions tasks, younger children showed a redundancy gain with integrated stimuli, but no gain was observed in the performances of the older subjects. With separated stimuli there was no redundancy gain at any age. These results were interpreted to mean that integrated stimuli are initially perceived as wholes by all subjects, but that features become more accessible with increasing age. Even so, attention remains constrained by stimulus structure. In contrast, separated stimuli are initially perceived as features at all ages, and the improvement in performance with increasing age is attributable to the increasing command of attentional resources that accompanies development. Our discussion of these findings focuses on three issues: multiple trends in perceptual development, the characteristics of an adequate theory of perceptual representation and processing, and a comparison of the separability hypothesis and other developmental accounts of perceptual development.     

Predicting emotional concomitants of learned helplessness: The role of motivational orientation

Previous theoretical and empirical analyses indicate that an extrinsic motivational orientation, i.e., performing activities to please others or concern with criticism, predicts the cognitive and behavioral deficits associated with learned helplessness. Conversely, intrinsically motivated students, who perform activities for the inherent pleasure of mastery over challenge, have been shown to be virtually resilient to successive failure experiences and even show a facilitation effect. However, research has not yet addressed the extent to which motivational orientation predicts the emotional deficits associated with helplessness—namely, depression and a maladaptive attributional style. Furthermore, no research has examined the relative predictability of these variables to investigate subjects' feelings after an experimental manipulation of failure. The present research found support for the proposition that an extrinsic motivational orientation predicts depression and the Expanded Attributional Style Questionnaire. More importantly, our findings demonstrated that an extrinsic motivational orientation was a more reliable predictor of subjects' feelings after a failure manipulation than either depression or a maladaptive attributional style. These findings are discussed in light of intervention strategies to attenuate the development of an extrinsic motivational orientation in students.     

Sports specific metacognitions and competitive state anxiety in athletes: A comparison between different sporting types

This study investigated the relationship between sport related metacognitions with state anxiety dimensions, and compared how sporting categories affected these variables, among an online sample of athletes (N = 187). A MANOVA revealed there were significant differences between sporting types in metacognitive beliefs relating to the utility of rumination and arousal, the need to control thoughts, and levels of somatic anxiety. Correlations and multiple regressions showed that that in contrast to the relationships with self-confidence, cognitive and somatic state anxiety were positively associated with specific dysfunctional metacognitive beliefs, but negatively related to metacognitive processes. Overall, these findings highlight that: (a) athletes might adopt metacognitions to meet the different cognitive demands of sport types; and (b) metacognitions are in part responsible for the occurrence of state anxiety and self-confidence during competitions. The findings of this study have implications toward how researchers and sports practitioners approach the comprehensive nature of competitive anxiety.     

Early cognitive development and parental education

Relations between cognitive development in infancy and early childhood, and parental education were examined. Previous research has found little association between measures of the parenting environment, including parental education and socio‐economic status (SES), and cognitive development in infants and children under 2 years of age. However, the earlier studies may not have reliably measured individual differences in cognitive abilities, thus, there is uncertainty as to what age elements in the parental environment affect cognitive development. Seventy‐six infants were tested on a range of cognitive tasks at 3‐month intervals between the ages of 9 and 18 months. Information on parental education (a component of SES) was collected. Seventy‐one of the children returned at 27 months and completed the Bayley Scales of Infant Development, Mental Scale, which was used as an outcome measure for the earlier tasks. The findings present a clear indication that cognitive development in early childhood is affected by the parenting environment, at least from as early as 12 months.

Threat Vigilance in Child Witnesses of Domestic Violence: A Pilot Study Utilizing the Ambiguous Situations Paradigm

Research has found that children exposed to family violence exhibit higher rates of maladjustment. We review relevant literature on family violence, marital conflict, and cognitive factors implicated in child behaviour problems. A bias toward perceiving threat in ambiguous contexts has been identified as one factor mediating both aggressive and anxious behaviour disorders. We conducted a study utilizing the ambiguous situations paradigm to assess whether children exposed to violent spousal conflict were more likely than children not exposed to violence (divided into children with an externalizing behaviour disorder and non-clinic children) to perceive threat in two classes of ambiguous situations: Peer and Inter-Parental. The results indicated that children exposed to violent spousal conflict perceived more threat in parental situations than either of the other two groups. A number of considerations were taken into account given the exploratory nature of the study, particularly sample limitations. We conclude with suggestions for improvements to the research design and the further relevance of exploring cognitive factors involved in the adjustment of children from backgrounds of violence.     

Home correlates of aggression in preschool

Is aggressive behaviour in preschool more closely related to individual characteristics of the child as assessed at home, to aspects of mother-child interaction, or to the motherchild relationship? The issue was studied in three replications. Aggression in preschool was related to temperamental characteristics in girls but not boys, and to Self-esteem. There were very few significant correlations between aspects of mother-child interaction and hostility in preschool, but hostility with peers was related to the absence of positive or presence of mildly negative interactions with the sibling. Aggression in preschool was related to an aspect of the mother-child relationship; least aggression was shown by those childred whose mothers used warmth and control more or less “in balance” (authortative Mothers). Such children also differed in other aspects of the mother-child relationship, and these provided some explanation of those children who appeared to be exceptions to the “balance” hypethesis. © 1993 Wiley-Liss, Inc.     

Resurgence as Choice in Context: Treatment duration and on/off alternative reinforcement

Resurgence as Choice (RaC) is a quantitative theory suggesting that an increase in an extinguished target behavior with subsequent extinction of an alternative behavior (i.e., resurgence) is governed by the same processes as choice more generally. We present data from an experiment with rats examining a range of treatment durations with alternative reinforcement plus extinction and demonstrate that increases in treatment duration produce small but reliable decreases in resurgence. Although RaC predicted the relation between target responding and treatment duration, the model failed in other respects. First, contrary to predictions, the present experiment also replicated previous findings that exposure to cycling on/off alternative reinforcement reduces resurgence. Second, RaC did a poor job simultaneously accounting for target and alternative behaviors across conditions. We present a revised model incorporating a role for more local signaling effects of reinforcer deliveries or their absence on response allocation. Such signaling effects are suggested to impact response allocation above and beyond the values of the target and alternative behaviors as longer-term repositories of experience. The new model provides an excellent account of the data and can be viewed as an integration of RaC and a quantitative approximation of some aspects of Context Theory.     

The role of the infant mental health therapist in the framework of preventive mental health

The role of the infant mental health therapist is differentiated from that of other infant interventionists as being a secondary prevention treatment approach employing the techniques of long-term, insight-oriented psychotherapy. Such an approach encourages the caregiver to recall his or her own childhood experiences and conflicts to gain an understanding of feelings directed at his or her own baby. The prevention models of Caplan are considered as is the development of the work of Fraiberg and her colleagues.     

Teachers' perceptions of the frequency and seriousness of violations of ethical standards

Despite nationwide efforts to professionalize public-school teaching, little attention has been given to the matter of standards of professional conduct for teachers. The authors examined teachers' perceptions of the frequency and seriousness of different categories of teacher misconduct. They administered a 34-item questionnaire to 235 school professionals in northwestern South Carolina. For each item, respondents rated the extent to which they agreed or disagreed that the behavior occurred frequently and represented a serious violation of professional ethics. Factor analysis of the ratings of seriousness yielded 3 domains of ethical concerns: (a) student-teacher boundary violations, (b) carelessness in behavior, and (c) subjectivity in grading and instruction. Teachers rated boundary violations as the most serious but least common violations and carelessness in behavior as the most frequent but least serious violation. Problems of subjectivity in grading were rated as moderately frequent and moderately serious. The authors found no differences between male and female teachers or between elementary and secondary teachers in their ratings of the seriousness or frequency of any of the 3 groups of ethical concerns. The authors discuss implications for development of a national code of teacher conduct.
