Verb Comprehension Deficits in Probable Alzheimer's Disease

Studies of lexical comprehension in probable Alzheimer's disease (pAD) have focused almost exclusively on nouns. In the following preliminary study, we examined whether lexical comprehension for verbs is also impaired in 25 pAD patients. The semantic meaning of motion verbs, cognition verbs, and perception verbs was assessed with a triadic comparison task. Structural meaning associated with these verbs was evaluated by asking the patients to judge the coherence of sentence frames that accept these verbs naturally or awkwardly. We found that pAD patients are significantly impaired at identifying semantic relations among verbs. pAD patients also encountered significantly more difficulty judging the coherence of sentences than control subjects. Correlation and regression analyses demonstrated that semantic characteristics of verbs are projected from the verbs' sentence frames in control subjects, but there was minimal evidence for such a structural–semantic relationship in pAD. We consider several possible explanations for our preliminary observations of an impairment that has consequences for processing both semantic and structural aspects of verb meaning.     

Free classification: Element-level and subgroup-level similarity

Subjects classified sets of multidimensional stimuli into two groups in any way they wished. The sets were composed of 6 or 12 stimuli: 2 or 4 instances of 3 different stimuli (e.g., 2 blue circles, 2 green circles, 2 red circles). There were striking individual differences in the preferred classification. Some subjects maximized the similarity between subgroups by matching the composition of the subgroups--one instance of each stimulus was placed in each group. The other subjects maximized the similarity among stimuli within each subgroup by placing similar stimuli in each group (the blues and greens in one group, the reds in the other). The nature of the stimuli as well as the relationships among the three stimuli had little effect on classification. In this case, cognitive styles specific to individuals but general across diverse dimensions and stimulus sets determined classification.     

CAUCASIAN LESBIANS' USE OF PSYCHOTHERAPY: A Matter of Attitude?

Evidence suggests that a high proportion of lesbians seek psychological counseling. This study represents an empirical investigation of the disproportionate use of mental health services by lesbians, focusing on the hypothesis that lesbians place a greater value on psychotherapy than do nonlesbian women. Participants (100 lesbians and 309 nonlesbian women, 97% Caucasian) completed Surgenor's revision of the Attitudes Toward Seeking Professional Psychological Help Scale. Results indicate that the lesbian group had a significantly more positive attitude toward seeking psychological counseling than did the nonlesbian sample, regardless of whether or not they had experienced psychological counseling.     

Physical activity status of academic professors during their early career transition: an application of the theory of planned behavior

Life-transitions (e.g. parenthood) have been linked to physical inactivity, yet the topic requires further exploration. In this study, we evaluated changes in the physical activity (PA) of adults during their early career transition using retrospective analysis and the theory of planned behavior. Recruitment from January to March 2010 yielded a random sample of 267 assistant professors, ages 25-44, employed within the last five years. Repeated measures analysis of variance (RM ANOVA) concluded that PA declined across the transition (d?=?0.36-0.43) and was further attenuated by marriage, work hours, and parenthood status. Discriminant function analysis (DFA) identified specific behavioral and control correlates about PA enjoyment, limited time, inconsistent schedule, work demands, and job pressures to distinguish between those who remained active from those who did not across the transition. PA interventions administered prior to career transitions may be needed to prevent physical inactivity.     

Volunteer Mentoring Relationships With Minority Youth: An Analysis of Same‐ Versus Cross‐Race Matches1

Despite the growth of youth mentoring programs in recent years, key questions remain regarding the relative importance of making matches on the basis of shared racial background. Both sides of the argument regarding racial matching are presented, followed by a comparison of the effects of same‐ vs. cross‐race matches involving minority youth (N= 476). Minority adolescents were less likely to report initiating alcohol when placed in cross‐race matches. In addition, minority boys in same‐race matches reported smaller decrements in scholastic competence and self‐worth than did minority boys in cross‐race matches. Minority girls in same‐race matches reported smaller decrements in school value and self‐worth than did minority girls in cross‐race matches. Youth, parent, and caseworker impressions of the 2 relationship types largely converged, but the few impressions that differed tended to favor cross‐race matches. The methodological limitations and implications of this study are discussed.     

Why Clinical Psychology Needs to Engage in Community‐Based Approaches to Mental Health

The aim of this article is to advocate for clinical psychology to engage with community‐based approaches to mental health. This engagement will be challenging given community work is antithetical to the individualism that defines much of clinical psychology. It would also result in a direct challenge to the core tenets of our profession, including an emphasis on individualism, psychopathology, and expert‐driven intervention. We need clinical psychology, however, to decolonise itself to respond to the needs of Aboriginal communities and those from non‐Western collectivist cultures. We also need clinical psychology to consider the sociopolitics of human distress and lend itself to social action for complex problems. Specific examples of community‐based practices will be provided, focusing specifically on those that relate to mental health. Implication for the reform of research methodologies and classroom pedagogies will also be discussed.     

The Questioning Process in Maudsley Family-Based Treatment. Part 1: Deviation Amplification

Maudsley family based treatment (FBT) continues to demonstrate promising evidence in the treatment of adolescent presentations of anorexia nervosa. In the earlier stages of this treatment modality, the process of empowering families, and in particular, helping parent to follow their natural instincts in making united decisions around re-feeding their child is critical. This paper aims to provide FBT practitioners with structured interviewing guidelines around the amplification of familial interactions around food, drawing on existing familial strengths and therefore empowering parents and families in their process of change. The questioning skills outlined are discussed in light of the theoretical tenets of the Maudsley FBT model.     

Rewards and creative performance: a meta-analytic test of theoretically derived hypotheses

Although many scholars and practitioners are interested in understanding how to motivate individuals to be more creative, whether and how rewards affect creativity remain unclear. We argue that the conflicting evidence may be due to differences between studies in terms of reward conditions and the context in which rewards are offered. Specifically, we examine 5 potential moderators of the rewards-creative performance relationship: (a) the reward contingency, (b) the extent to which participants are provided information about their past or current creative performance, (c) the extent to which the reward and context offer choice or impose control, (d) the extent to which the context serves to enhance task engagement, and (e) the extent to which the performance tasks are complex. Using random-effects models, we meta-analyzed 60 experimental and nonexperimental studies (including 69 independent samples) that examined the rewards-creativity relationship with children or adults. Our results suggest that creativity-contingent rewards tend to increase creative performance-and are more positively related to creative performance when individuals are given more positive, contingent, and task-focused performance feedback and are provided more choice (and are less controlled). In contrast, performance-contingent or completion-contingent rewards tend to have a slight negative effect on creative performance.     

Understanding action control: predicting physical activity intention-behavior profiles across 6 months in a Canadian sample.

Intention is theorized as the proximal determinant of behavior in some theories of motivation, but the need to understand predictors of action control (i.e., translating an intention into behavior) is warranted to tailor physical activity intervention efforts. The purpose of this study was to examine constructs of the transtheoretical model of behavior change (TTM) as predictors of physical activity intention-behavior profiles across 6 months in a large Canadian sample (N = 1,192). Results showed that 5 of the 8 possible intention-behavior profiles had a substantial number of participants: nonintenders, unsuccessful adopters, successful adopters, unsuccessful maintainers, and successful maintainers. Constructs of the TTM distinguished (p < .01) intention-behavior profiles. Self-efficacy and the behavioral processes of change were particularly good predictors of action control (p < .01), but disaggregated beliefs and processes identified specific intervention targets for successful physical activity adoption and maintenance. The results validate that both action planning and action control are important when understanding physical activity behavior.
