Friends with benefits: on the positive consequences of pet ownership

Social support is critical for psychological and physical well-being, reflecting the centrality of belongingness in our lives. Human interactions often provide people with considerable social support, but can pets also fulfill one's social needs? Although there is correlational evidence that pets may help individuals facing significant life stressors, little is known about the well-being benefits of pets for everyday people. Study 1 found in a community sample that pet owners fared better on several well-being (e.g., greater self-esteem, more exercise) and individual-difference (e.g., greater conscientiousness, less fearful attachment) measures. Study 2 assessed a different community sample and found that owners enjoyed better well-being when their pets fulfilled social needs better, and the support that pets provided complemented rather than competed with human sources. Finally, Study 3 brought pet owners into the laboratory and experimentally demonstrated the ability of pets to stave off negativity caused by social rejection. In summary, pets can serve as important sources of social support, providing many positive psychological and physical benefits for their owners.     

Contextual interference and augmented feedback: is there an additive effect for motor learning?

Learning to perform a skilled behavior is affected by the context of the practice session and the frequency of augmented feedback. We studied the combined effect of these variables in the acquisition of a ballistic, bi-directional lever movement pattern involving four different target locations as measured by performance in practice, retention, and transfer tests. Augmented feedback was presented in either an every-trial or a faded schedule during random and blocked practice. Consistent with the contextual interference effect, the blocked practice group produced lower errors in acquisition, but the random practice group outperformed the blocked practice group in both retention and transfer. In contrast, faded feedback did not have a beneficial effect on learning and degraded learning when provided during blocked practice. While the results were consistent with previous findings of random and blocked practice, they were not consistent with previous findings of reduced feedback frequencies.     

Upbeat and happy: arousal as an important factor in studying attention

The present study examined the effects of music-induced mood changes on different components of visual attention. Affective valence (positive vs. negative) and arousal (high vs. low) were manipulated by having participants listen to one of four versions of a Mozart Sonata that varied in mode (major or minor) and tempo (fast or slow). Attention was measured in three domains-alerting, orienting, and executive control. Affective valence and arousal had an effect on executive control, but not on alerting or orienting. Individuals who experienced positive valence had less efficient control over their responses than those who experienced negative valence, but only when arousal levels were high. Positive and negative valence did not influence executive control measures when arousal levels were low. These findings demonstrate that affective valence and arousal interact with one another to influence the processing of items in visual attention.     

Endogenous estradiol is associated with verbal memory in nondemented older men

This study examined the relationship between endogenous hormones and cognitive function in nondemented, ethnically-diverse community-dwelling older men enrolled in the Einstein Aging Study (EAS). All eligible participants (185 men, mean age=81 years) received neuropsychological assessment (Free and Cued Selective Reminding Test (FCSRT), Logical Memory (LM), Trail Making Test B (TMTB), block design (BD)) and provided blood samples for hormonal assays (total estradiol, total testosterone, calculated free testosterone index). Linear regression analysis adjusted for age, education, body mass index, and cardiovascular comorbidities indicated that men with high levels of total estradiol demonstrated better FCSRT verbal memory performance (β=0.17, p<0.02) compared to men with lower levels of total estradiol. The results remained unchanged when the model was further adjusted for ethnicity. We did not detect an association between testosterone and cognitive performance. These findings indicate that high levels of total estradiol in older men are associated with better performance on a cue-based, controlled learning test of verbal memory that is a sensitive predictor of dementia.     

Early literacy individual growth and development indicators (EL-IGDIs): growth trajectories using a large, internet-based sample

Early literacy individual growth and development indicators (EL-IGDIs) assess preschoolers' expressive vocabulary development and phonological awareness. This study investigated longitudinal change in EL-IGDIs using a large (N=7355), internet-based sample of 36- to 60-month-old United States preschoolers without identified risks for later achievement delays. There were three major findings. First, results identified sensitivity to longitudinal change for all three EL-IGDIs (i.e., Picture naming, Rhyming, and Alliteration). Second, results demonstrated age-related differences in growth rates between 3- and 4-year-olds, especially for Rhyming and Alliteration. Third, preliminary national norms were reported. Discussion highlights the need for research examining the sensitivity of EL-IGDIs for younger preschoolers.     

Politics,lack of career progress,and work/home conflict: Stress and strain for working women

This study examines the stress experienced by working women in terms of politics, lack of career progress, and work/home conflicts, the symptoms of distress and satisfaction associated with these stressors, and the organizational resources available for managing these demands. Subjects were 195 female personnel professionals. A different pattern of results emerged for politics and lack of career progress in contrast to work/home conflicts. Specifically, politics and lack of career progress were associated with greater strain symptoms and reduced satisfaction, and organizational resources were associated with lower levels of these stressors. Work/home conflicts were associated with greater strain symptoms, but were unrelated to satisfaction and organizational resources. This suggests that organizations identify the most effective targets of their resources to achieve beneficial results.     

Cognitive theory,cognitive impairment and clinical practice

The aim of this paper is to present a practical model for investigating cognitive impairment which integrates the experimental-cogaitive-information processing-theory and the psychometric-intellectual-abilities-tradition in psychology to understanding cognitive functioning. It reviews developments in cognitive theory in terms of Processes, complex and simple, such as Intelligence and Information Processing, and Factors of attained Level and Learning ability in the Verbal and Performance modalities. The Savage Cognitive Impairment Model (SCIM) is outlined and types of cognitive impairment defined. Measures of cognitive impairment relevant to clinical practice and research are presented.     

Personality through metaphor: Optimism, pessimism, locus of control, and sensation seeking

In two experiments, several personality attributes evident in metaphors people use to describe everyday experiences were examined. Subjects either generated (Experiment 1) or endorsed (Experiment 2) a metaphor that represented their views about six facets of their lives (e.g., work, relationships, graduating). In self-generated metaphors, content analyses of the metaphors revealed that attributes of optimism (e.g., looking forward to the future) and pessimism (e.g., cynicism) were significant components of metaphor content. Also, modest relationships were found between the themes of optimism contained within their metaphors and scores on an optimism scale of a questionnaire designed to evaluate the optimistic and pessimistic orientations. In a second study, subjects endorsed how strongly preselected metaphors represented important aspects of their lives. These preferences were significantly related to their scores on an optimism/pessimism instrument and a locus of control inventory. These results support the notion that metaphors, like other creative productions, may prove a useful vehicle for studying personality characteristics. They also provide evidence for the construct validity of the optimism and pessimism questionnaire.
