Effects of Stimulus Color,Pattern, and Practice on Sex Differences in Mental Rotations Task Performance

Redundant color information improved performance for both sexes on the Shepard Mental Rotations Task (MRT; Shepard & Metzler, 1971). Absolute score gains for women were larger than those for men; therefore, relative improvement was greater. Substantial practice effects, also favoring women, were apparent in both studies. Study 1 showed that redundant color improved performance by 0.25 SD. Study 2 demonstrated that redundant black-and-white pattern information did not have any effect; a second visuospatial channel, redundant color, was a critical factor in improving scores of men and women on difficult mental rotations tasks.     

Countering Perfectionism in Research on Clinical Practice. III: Implications for Randomized Designs of the Presence of Uncontrolled Interactions and Spontaneous Changes

In a crossover study, we took pre-test, post-first-treatment, and post-second-treatment measures of self-expressiveness (assertiveness) and of acute emotional distress while we successively trained different groups of students in assertiveness and group therapy exercises. Our (unfulfilled) expectations were straightforward: We thought that assertiveness training would produce specific improvement in self-expression measures with little impact on overall distress and that group therapy would produce specific improvement in general distress with little impact on assertiveness. Both treatments improved assertiveness and decreased distress. The fact that our treatments had impure effects enhanced the likelihood of Type II statistical errors and compromised the effectiveness of our design. In addition, quite surprisingly, assertiveness training selectively improved the mental health of women students, and group therapy selectively improved the assertiveness of men students more than the alternative treatment did. This interaction between gender and randomly administered experimental treatment procedures raises serious, generally important questions about the logic of statistically controlled experimentation that relies on randomization to eliminate the effects of uncontrolled, but relevant, variables.     

Eating Behavior Among Thais and Americans

A cross-cultural analysis of eating patterns was conducted to examine the possible relationship between eating style and obesity. Thai and American students were surveyed about such bad eating habits as eating between meals, eating too quickly, eating when not hungry, and eating in response to external food cues. Contrary to the learning model of obesity, which postulates a causal relationship between eating style and body size, American subjects reported significantly better eating habits than did their much thinner Thai counterparts. A within-culture comparison of the American subjects showed a less significant but similar trend, with obese subjects claiming to have better eating patterns than both thin and underweight subjects.     

Body-related pride in young adults: An exploration of the triggers,contexts, outcomes and attributions

This study explored body-related emotional experiences of pride in young adult males (n = 138) and females (n = 165). Data were collected using a relived emotion task and analyzed using inductive content analysis. Thirty-nine codes were identified and grouped into six categories (triggers, contexts, cognitive attributions, and affective, cognitive, and behavioral outcomes) for each of two themes (hubristic and authentic pride). Hubristic pride triggers included evaluating appearance/fitness as superior. Cognitions centered on feelings of superiority. Behaviors included strategies to show off. Triggers for authentic pride were personal improvements/maintenance in appearance and meeting or exceeding goals. Feeling accomplished was a cognitive outcome, and physical activity was a behavioral strategy. Contexts for the experience of both facets of pride primarily involved sports settings, swimming/beach, and clothes shopping. These findings provide theoretical support for models of pride as it applies to body image, and advances conceptual understanding of positive body image.     

Are age-related changes in cognitive function driven by age-related changes in sensory processing?

Although there has been keen interest in the association among measures of sensory function and cognitive function for many years, in general, measures of sensory function have been confined to one or two senses and measures of threshold sensitivity (acuity). In this study, rigorous psychophysical measures of threshold sensitivity, temporal gap detection, temporal order identification, and temporal masking have been obtained, in hearing, vision, and touch. In addition, all subjects completed 15 subtests of the Wechsler Adult Intelligence Scale, 3rd edition (WAIS–III). Data were obtained from 245 adults (18–87 years old) for the WAIS–III and for 40 measures of threshold sensitivity and temporal processing. The focus in this report is on individual differences in performance for the entire data set. Principal-components (PC) factor analysis reduced the 40 psychophysical measures to eight correlated factors, which were reduced further to a single global sensory processing factor. Similarly, PC factor analysis of the 15 WAIS–III scores resulted in three correlated factors that were further reduced to a single global cognitive function factor. Age, global sensory processing, and global cognitive function were all moderately and significantly correlated with one another. However, paired partial correlations, controlling for the third of these three measures, revealed that the moderate correlation between age and global cognitive function went to zero when global sensory processing was controlled for; the other two partial correlations remained intact. Structural models confirmed this result. These analyses suggest that the long-standing observation of age-related changes in cognitive function may be mediated by age-related changes in global sensory processing.     

Methods for Assessing Quality of Life and Well-Being in Frail Older People

The appropriateness, reliability and convergence of differing methods and associated instruments for the assessment of quality of life and well-being in frail older people was examined in 60 ( S 65 years of age) nursing home residents. The feasibility of measuring quality of life and well-being via a variety of instruments was explored through observation (an adaptation of Dementia Care Mapping), structured interview (Schedule for the Evaluation of Individual Quality of Life - Direct Weighting), and proxy questionnaire (Pleasant Events Schedule - Alzheimer Disease; Apparent Emotion Rating Scale). The observational assessment and Pleasant Events Schedule demonstrated good reliability. Significant associations were found between well-being as assessed by observation, and active social interaction and engagement in recreation as assessed by observation, quality of life as assessed by structured interview, and enjoyment of activities as assessed by proxy questionnaire. These findings indicate the importance of social activity in later life, and the potential of different approaches for the appropriate assessment of key aspects of quality of life in frail older people.     

Religious belief,age, and sexual orientation on attributions of younger and older gay and heterosexual men

Using 4 vignettes and 20 response items, this exploratory study investigated attributions about older or younger gay or heterosexual men with a history of multiple sex partners, substance abuse, and legal problems. The character is diagnosed with a terminal illness and two options for care: no treatment or an aggressive treatment protocol with a small chance of recovery. When controlling for respondents’ (N?=?324) religious identification, frequency of attendance at religious services, and ethno-cultural identification, a General Linear Model was significant (F?=?57.014, df?=?20, p?<?.001). Differences in the vignette responses centred on perceptions of quality of life, the character's lifestyle, and suicide.     

Religion, Spirituality and Therapy: Implications for Training

Religion and spirituality are recognized coping resources but are neglected in psychological training and practice. However, religion and spirituality can be successfully used to cope with psychological disorders, prevent unhealthy behaviors and promote resilience. This study explored and described two questions regarding the concepts of the terminology religion and spirituality, and the perceptions of the use of religion and spirituality in therapy. Purposive sampling was utilized in a qualitative study of 15 registered psychologists, and data were analyzed using Tesch’s model of qualitative content analysis. The concepts religion and spirituality appear difficult to define but the importance of their use as coping mechanisms in their own and their clients’ lives was recognized. These findings have implications for professional training.     

The impact of object carriage on independent locomotion

The current study examined whether carrying objects in one's hands influenced different parameters associated with independent locomotion. Specifically, 14- and 24-month-olds walked in a straight path under four conditions of object carriage – no object (control), one object carried in one hand (one object-one hand), two objects carried in each of the hands (two objects-two hands), and one object carried in both hands simultaneously (one object-two hands). Although carrying objects failed to influence a variety of kinematic parameters of gait, it did affect children's arm postures, with children adopting less mature arm positions when carrying objects. Finally, arm position was related to walking skill, but only for older children when they were not carrying objects. These findings indicate that although a relation does exist between arm positions and gait parameters, this relation is easily disrupted by carrying loads, even small ones.
