Cross-lateralisation in children with attention-deficit/hyperactivity disorder and motor skill performance

Cross-lateralisation and increased motor difficulties have been reported in children with attention-deficit/hyperactivity disorder (ADHD). Nevertheless, the question of how crossed (i.e. mixed preference) or uncrossed (i.e. same side preference) lateralisation impacts motor performance in children with ADHD has yet to be examined. In this study, previously validated observational measures of hand and foot preference were used to identify right-handed children with ADHD who display cross- (n = 29) and uncross-lateralisation (n = 31). An uncross-lateralised typically developing (TD) group (n = 32) was also identified, and included as a control. Motor performance was assessed with seven valid and reliable fine and gross motor tasks performed with both preferred and non-preferred limbs. Group, task and sex-related effects were examined. Findings revealed that male (but not female) cross-lateralised children with ADHD performed significantly worse, respectively, in two of the fine motor tasks (spiral tracing [p < .01], and dot filling [p < .05]). Results suggest that cross-lateralised hand and foot preference may affect complex motor skills in male children with ADHD. Furthermore, characteristics of ADHD may manifest differently in male and female children. Findings highlight the importance of considering both hand and foot preference when targeting motor interventions for children with ADHD.     

“Other” behavior and the DRO: The roles of extinction and reinforcement

Jessel et al. (2015) provided some evidence to suggest that “other” behavior is strengthened in the differential reinforcement of other behavior (DRO). The present study is a systematic replication of the Jessel et al. procedures. The effects of DRO and extinction on target responding, target-other responding (a response with an established history of reinforcement), and nontarget-other responding emitted by children with intellectual and developmental disabilities and children with no known diagnoses were compared. Other behavior increased in at least one DRO condition for each participant, suggesting that other behavior increases when using DRO, at least initially. Under extinction, target responding and target-other responding decreased to low rates for three of the five participants; however, rates of nontarget-other responding were elevated compared to the DRO condition. These results suggest that increased rates of target-other responding and nontarget-other responding during the DRO condition may be a result of extinction-induced variability.     

Making Sense of the Hands and Mouth: The Role of “Secondary” Cues to Meaning in British Sign Language and English

Successful face-to-face communication involves multiple channels, notably hand gestures in addition to speech for spoken language, and mouth patterns in addition to manual signs for sign language. In four experiments, we assess the extent to which comprehenders of British Sign Language (BSL) and English rely, respectively, on cues from the hands and the mouth in accessing meaning. We created congruent and incongruent combinations of BSL manual signs and mouthings and English speech and gesture by video manipulation and asked participants to carry out a picture-matching task. When participants were instructed to pay attention only to the primary channel, incongruent “secondary” cues still affected performance, showing that these are reliably used for comprehension. When both cues were relevant, the languages diverged: Hand gestures continued to be used in English, but mouth movements did not in BSL. Moreover, non-fluent speakers and signers varied in the use of these cues: Gestures were found to be more important for non-native than native speakers; mouth movements were found to be less important for non-fluent signers. We discuss the results in terms of the information provided by different communicative channels, which combine to provide meaningful information.     

PERCEPTIONS OF SEX DISCRIMINATION AMONG FEMALE UNIVERSITY FACULTY AND STAFF

Sixty faculty and staff women at a mid–sized university were surveyed to determine the extent to which they perceived sex discrimination. Faculty women perceived sex discrimination more than did staff women and were less likely to believe that academia was a meritocracy. Differences in perception of sex discrimination were also found based upon the gender composition of the departments. Women in departments that were male–dominated were less likely to perceive sex discrimination and more accepting of the meritocracy notion than were women in departments that were not male–dominated.     

NONCONSCIOUS EFFECTS OF POWER ON BASIC APPROACH AND AVOIDANCE TENDENCIES

According to the approach/inhibition theory of power (Keltner, Gruenfeld, & Anderson, 2003), having power should be associated with the approach system, and lacking power with the avoidance system. However, to this point research has focused solely on whether power leads to more action, particularly approach-related action, or not. In three experiments, we extend this research by exploring the direct, unintentional relation between power and both approach and avoidance tendencies. Priming high power led to greater relative BAS strength than priming low power, but did not affect the BIS (Exp. 1). High-power priming also facilitated both simple and complex approach behavior, but did not affect avoidance behavior (Exp. 2-3). These effects of power occurred even in power-irrelevant situations. They also cannot be explained by priming of general positive versus negative constructs, nor by changes in positive, negative, approach-related, or avoidance-related affect.     

The Nonconscious Nature of Power: Cues and Consequences

Power – asymmetric control over valued resources – is a fundamental dimension of social relations. Classical conceptualizations of power emphasize its conscious nature. In this review, we reveal how power often operates nonconsciously and identify the different methods and paradigms used to activate or create a psychological sense of power outside of conscious awareness. First, we establish that cues of power are often attended to nonconsciously, which explains why people can be so accurate at determining their own and others’ level of power yet so inaccurate at identifying the specific cues diagnostic of possessing power. Second, we discuss how people are often unaware of how the possession of power fundamentally alters basic psychological and behavioral tendencies and describe the range of methodologies – roles, cues, episodic recall, conceptual priming – used to identify the nonconscious effects of power. Power produces two broad types of effects: It increases abstraction in thought and approach in behavior, both of which make individuals more focused on their own goals and internal states. Like other psychological constructs and processes, even ones that are inherently social and relational, power’s cues and consequences do not have to be conscious for its profound influence on basic psychological and interpersonal processes to emerge. We discuss the implications of the nonconscious nature of power for limiting the corrupting, dark side often revealed among the powerful.     

The Relation of Personal Epistemology to Parenting Style and Goal Orientation in College Mothers

This study sought to establish the relevance of mothers’ epistemic beliefs to their parenting style and preferred academic goals for their child. College mothers (N = 163) from primarily working class families completed a variety of self-report measures including a modified version of Schommer’s [(1990). Journal of Educational Psychology, 82, 498–504] Epistemological Beliefs Questionnaire, the Parental Attitudes Questionnaire-Revised [Reitman, Rhode, Hupp, & Altobello (2002). Journal of Psychopathology and Behavioral Assessment, 24(2), 119–127], and several goal orientation scales. Results indicated that a view of learning as effortful and under the learner’s control and a view of knowledge as actively constructed were associated with an authoritative parenting style and with a preference for their child to focus on learning, improvement, and effort in approaching academic tasks. By contrast, a view of learning as quick, straightforward, relatively passive and as based in innate constraints and a view of knowledge as consisting of discreet, unambiguous facts were associated with authoritarian and permissive styles and the adoption of performance goals for one’s child. Portions of this study were presented at the annual meeting of the Society for Research in Child Development in Atlanta, April, 2005.     

Romanticism as a function of age, sex, and ethnicity

This study examined the association between romanticism (operationalized as mean score on the Romantic Beliefs Scale) and age, sex, and ethnicity in a large community sample (N = 436). Age was negatively correlated with romanticism scores; as age increased, romanticism scores decreased. No sex differences were found; men and women had similar, moderate scores. Although ethnicity largely was unrelated to romanticism, Asian/Pacific Islander participants were significantly more romantic than were African-American participants.
