Ambient sensory conditions: modification of receptive speech deficits in left-side stroke patients using bright light

Previous research has demonstrated the potential for the use of ambient sensory conditions to improve cognitive functioning. Both light and sound have been shown to improve task performance in various populations including children, younger adults, and elderly participants; however, these cognitive gains may possibly be offset by detrimental cardiovascular reactivity in elderly persons. We now have some evidence for ambient sensory conditions affecting cognitive function following left- or right-side cerebrovascular accidents.     

Temporal variations in visual completion: a reflection of spatial limits?

The completion of partly occluded objects appears instantaneous and effortless, but empirically takes measurable time. The current study investigates how amount of occlusion affects the time course and mechanisms of visual completion. Experiment 1 used a primed-matching paradigm to determine completion times for objects occluded by various amounts. Experiments 2 and 3 used a dot-localization paradigm to probe completed contour representations for a qualitative shift above some spatial limit. The results demonstrate that time to completion rises with amount of occlusion. Nonetheless, the visual system can complete highly occluded objects, even when the occlusion renders visible contours nonrelatable. Furthermore, prolonged completion times for highly occluded objects do not result from a breakdown of low-level interpolation processes: The same contour completion mechanism operates on objects occluded by different spatial extents.     

Social achievement goals: the nature and consequences of different orientations toward social competence

The proposition that achievement goals are applicable to the social domain was examined in four studies. Study 1 established that different orientations toward developing or demonstrating social competence can be seen in individuals' responses to open-ended questions about their social goals and social competence. Studies 2 through 4 evaluated a new survey measure of social achievement goals. Exploratory and confirmatory factor analyses confirmed the hypothesized model of social achievement goals. Convergent and discriminant validity for the new measure of social achievement goals was established. In line with hypotheses, a social development goal was associated with adjustment and a social demonstration-avoid goal was associated with maladjustment both concurrently and longitudinally. A social development goal also was positively related to instructor ratings of students' social adjustment in small classroom settings. A social demonstration-approach goal was most often unrelated to adjustment. The importance of social achievement goals for a comprehensive understanding of social motivation and adjustment is discussed.     

Labeling guides object individuation in 12-month-old infants

A new manual search method was used to investigate the impact of naming on object individuation in 12-month-old infants. In Experiment 1, on a two-word trial, an experimenter looked into a box while the infant was watching and provided two labels (e.g., "Look, a fep!" and "Look, a wug!"). On a one-word trial, the experimenter instead repeated the same label (e.g., "Look, a zav!"). After the infant retrieved one object from the box, subsequent search behavior was recorded. Infants searched more persistently (i.e., for a longer duration) after hearing two labels than one, suggesting that hearing two labels led the infants to expect two objects inside the box. In Experiment 2, infants' search behavior did not differ depending on whether they heard one or two emotional expressions, suggesting that the facilitation effect observed in Experiment 1 may be specific to linguistic expressions. Thus, we provide the first evidence that infants as young as 12 months are able to use intentional and referential cues to guide their object representations. These findings also suggest that a rudimentary version of the mutual-exclusivity constraint may be functional by the end of the first year.     

From referral to disposition: case processing in seven mental health courts

The number of mental health courts in the United States is rapidly increasing, from one in 1997 to nearly 100 in 2004. However, to date there is comparatively little research regarding these specialty courts. The present study reports data on the referral and disposition decision-making processes of seven mental health courts. Information on all referrals to the seven courts over a three-month period was gathered. Results show that, in comparison with individuals involved in the criminal justice system, mental health court clients are more likely to be older, White, and women than individuals in the general criminal justice system. Furthermore, this over-representation occurs at the point of referral, rather than at the point of the court's decision to accept or reject a referral. In addition, the length of time from referral to diversion is much longer in these mental health courts than in other types of diversion programs. Implications of these findings are discussed.     

Acute stress disorder: a synthesis and critique

The diagnosis of acute stress disorder (ASD) was introduced to describe initial trauma reactions that predict chronic posttraumatic stress disorder (PTSD). This review outlines and critiques the rationales underpinning the ASD diagnosis and highlights conceptual and empirical problems inherent in this diagnosis. The authors conclude that there is little justification for the ASD diagnosis in its present form. The evidence for and against the current emphasis on peritraumatic dissociation is discussed, and the range of biological and cognitive mechanisms that potentially mediate acute trauma response are reviewed. The available evidence indicates that alternative means of conceptualizing acute trauma reactions and identifying acutely traumatized people who are at risk of developing PTSD need to be considered.     

Cuing interacts with perceptual load in visual search

We tested the strong form of the perceptual-load hypothesis, which posits that the amount of perceptual load is the only factor determining whether attention can be effectively focused. Participants performed a visual search task under conditions of low and high load and with either a 100% valid spatial cue or no spatial cue. With no cue, participants showed evidence of processing to-be-ignored stimuli when perceptual load was low but not when it was high, consistent with the perceptual-load hypothesis. However, with a 100% valid spatial cue, participants showed little evidence of processing to-be-ignored stimuli, even when perceptual load was low. These results suggest that although perceptual load may be an important factor in attentional selectivity, load alone is not sufficient to explain how and when selective attention is effective.     

Encouraging Occupation: A Systematic Review of the Use of Life Review and Reminiscence Therapy for the Treatment of Depressive Symptoms in Older Adults

The present systematic review investigates the efficacy of both life review and reminiscence therapy interventions in the treatment of depressive symptoms in older adults. A systematic review of the literature was conducted using three databases: Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, and PsycINFO. Six studies met the inclusion criteria, and pertinent variables were extracted for data analysis. In all six articles, the reminiscence therapy or life review intervention was found to be effective in the treatment of depressive symptoms in older adults. These interventions are appropriate for use in occupational therapy practice, as occupational therapists are well-equipped to treat the psychosocial needs of individuals.     

Something Old, Something New: Evidence of Self-Accommodation to Gendered Social Change

Two studies examined how individuals adapt the self to social trends—in particular, when the social roles of the gender ingroup change, do people readily leave behind traditional roles in favor of nontraditional roles? We hypothesized that self-relevant cognitions and behaviors would accommodate to societal change, and we found that this accommodation took the shape of greater acceptance of nontraditional roles alongside continued acceptance of traditional roles. Experiment 1 included 112 undergraduates from the Midwestern U.S. who learned about social change or social stability by reading articles ostensibly published in a newspaper. Individuals who learned about social change for their gender ingroup, relative to those learning about social stability, projected greater personal success in careers, particularly for gender-nontraditional careers. Experiment 2 examined behavioral responses to social change in a sample of 198 female undergraduates from the Midwestern U.S. Participants learned about social change or social stability and then chose to view either a website focused on physical appearance (i.e., traditional choice) or leadership (i.e., nontraditional choice). Behavioral responses to social change reflected accommodation to the anticipated social structure: Individuals who learned about social change chose to view information about nontraditional rather than traditional roles. These studies provide initial experimental evidence investigating how individuals adapt the self to the social structure.     

Specifying Links Between Executive Functioning and Theory of Mind during Middle Childhood: Cognitive Flexibility Predicts Social Understanding

The purpose of this study was to specify the development of and links between executive functioning and theory of mind during middle childhood. One hundred four 7- to 12-year-old children completed a battery of age-appropriate tasks measuring working memory, inhibition, flexibility, theory of mind, and vocabulary. As expected, spatial working memory and flexibility increased significantly with age, especially after 7 years. Moreover, flexibility predicted social understanding over and above the effects of age, vocabulary, working memory, and inhibition. Together, these findings highlight improvements in and tight relations between complex aspects of executive functioning and theory of mind during middle childhood and suggest that executive functioning and theory of mind are linked beyond their emergence in early childhood.
