Individual Differences in Arousal and Accessibility to Information in Memory

The authors conducted 9 experiments to test the hypothesis (S. Schwartz, 1975) that arousal influences the accessibility of information stored in memory. They investigated the relationship between arousal levels (as indexed by personality types) and the type of stimuli or cues presented during study or test. They predicted that low-arousal individuals (stable extroverted individuals in Experiments 1-3 and 5-9 and high-impulsive individuals in Experiment 4) would be influenced by semantic stimuli, whereas high-arousal individuals (neurotic introverted individuals in Experiments 1-3 and 5-9 and low-impulsive individuals in Experiment 4) would be influenced by physical (i.e., graphic, phonetic, or both) stimuli. They tested the arousal-accessibility hypothesis by using a variety of tasks including verbal discrimination, false recognition, cued recall, and paired associates. With the exception of the finding that stable extroverted participants performed better than neurotic introverted participants on an incidental associative-matching task (Experiment 3), the results from the verbal discrimination studies (1-5) did not support the hypothesis. In Experiment 6, the authors tested the hypothesis by using a false-recognition task. False alarms varied as a function of phonetic and semantic stimuli, but personality types were not differentially sensitive to the manipulation. The same was true for the cued-recall studies (Experiments 7 and 8); personality types were not differentially sensitive to the semantic and phonetic stimuli. Experiment 9 (paired-associate learning) was a replication of Schwartz's study. The authors found some support for the Schwartz hypothesis: Extraverted participants were adversely affected by semantic similarity. Overall, the findings did not provide much support for the arousal-accessability hypothesis.     

Occupational Therapy Students' Development of Therapeutic Communication Skills During a Service-Learning Experience

This qualitative study examined the effect community-based service-learning experiences had upon occupational therapy students' therapeutic communication skills and their application of theoretical concepts. After their semester-long course was completed, six students de-identified and voluntarily submitted their weekly reflective journals for retrospective analysis in accordance with Giorgi's strategies (1985 Giorgi , A. ( 1985 ). Phenomenology and psychological research . Pittsburgh , PA : Duquesne University Press . [Google Scholar], 1997 Giorgi , A. ( 1997 ). The theory, practice, and evaluation of the phenomenological method as a qualitative research procedure . Journal of Phenomenological Psychology , 28 , 235 – 261 .[Crossref] , [Google Scholar]). Two analysts identified eight themes: developing trust, establishing boundaries, communication, client-centered care, breakdown of preconceptions, increased self-awareness, power of pride, and power of occupation. Educators are urged to use service-learning experiences to facilitate student interpersonal skill development and integration of theoretical knowledge.     

Are anxiety and depression just as stable as personality during late adolescence? Results from a three-year longitudinal latent variable study

Although considerable evidence shows that affective symptoms and personality traits demonstrate moderate to high relative stabilities during adolescence and early adulthood, there has been little work done to examine differential stability among these constructs or to study the manner in which the stability of these constructs is expressed. The present study used a three-year longitudinal design in an adolescent/young adult sample to examine the stability of depression symptoms, social phobia symptoms, specific phobia symptoms, neuroticism, and extraversion. When considering one-, two-, and three-year durations, anxiety and personality stabilities were generally similar and typically greater than the stability of depression. Comparison of various representations of a latent variable trait-state-occasion (TSO) model revealed that whereas the full TSO model was the best representation for depression, a trait stability model was the most parsimonious of the best-fitting models for the anxiety and personality constructs. Over three years, the percentages of variance explained by the trait component for the anxiety and personality constructs (73-84%) were significantly greater than that explained by the trait component for depression (46%). These findings indicate that symptoms of depression are more episodic in nature, whereas symptoms of anxiety are more similar to personality variables in their expression of stability.     

Depleted parental psychological resources as mediators of the association of income with adherence and metabolic control

For adolescents with Type 1 diabetes, lower family income may be associated with poorer diabetes management through depleted parental psychological resources (i.e., higher parental depressive symptoms, lower parental acceptance). Adolescents (N = 252; 46% male) aged 10-14 years with Type 1 diabetes assessed the acceptance of their mother and father (e.g., "gives me the feeling that she likes me as I am"; "she doesn't feel she has to make me over into someone else"). Mothers provided information on family income and demographics. Both mothers and fathers reported their depressive symptoms. HbA1c scores were indexed via medical records. Lower family income was associated with higher (i.e., worse) HbA1c, more mother and father depressive symptoms, and less acceptance from both parents. Mediation analyses revealed that the relationship of lower family income with metabolic control occurred indirectly through lower maternal and paternal acceptance and lower adherence. Lower family income may impair the quality of parent--adolescent relationships that are beneficial for good diabetes management.     

Retrieval of past and future positive and negative autobiographical experiences

We studied retrieval-induced forgetting for past or future autobiographical experiences. In the study phase, participants were given cues to remember past autobiographical experiences or to think about experiences that may occur in the future. In both conditions, half of the experiences were positive and half negative. In the retrieval-practice phase, for past and future experiences, participants retrieved either half of the positive or negative experiences using cued recall, or capitals of the world (control groups). Retrieval practice produced recall facilitation and enhanced memory for the practised positive and negative past and future experiences. While retrieval practice on positive experiences did not impair the recall of other positive experiences, we found inhibition for negative past and future experiences when participants practised negative experiences. Furthermore, retrieval practice on positive future experiences inhibited negative future experiences. These positivity biases for autobiographical memory may have practical implications for treatment of emotional disorders.     

The impact of residential context on adolescents' Subjective Well being

The study investigates the impact of residential context on stressful events and Subjective Well being (Emotional and Psychological) in young people living in a deprived geographical area, and the mediating role of personal (Self‐Efficacy) and social (Social Support, Sense of Community) variables. A questionnaire was submitted to 297 subjects (48.5% males): 203 adolescents (14–19 years old) and 94 young adults (20–27 years old), from different socio‐economic (SES) levels. Results confirm the significant impact of the residential context on youngsters' perceived residential quality, Stress and Subjective Well being outcomes; such effect partly differs according to participants' gender and age. Adolescents are less satisfied of their living context and enjoy lower well being than young adults. Social resources (Friend and Family Support) significantly buffer the effect of a deprived residential context of youngsters' Well being, whereas personal resources (Self‐Efficacy) directly increase Well being levels.

Evaluating the invariance of the factor structure of the EPQ-R-N among adolescents

We examined the factor structure of the Neuroticism scale of the Eysenck Personality Questionnaire (EPQ-R-N; S. B. G. Eysenck, Eysenck & Barrett, 1985) and its factor invariance across sex and racial/ethnic groups in a sample of 1,979 adolescents. Using confirmatory factor analyses, we compared a hierarchical model to previous models of the EPQ-R-N and to single-factor and 3-factor structures. The hierarchical factor structure in which a general factor coexists with 3 group factors (depression, social concerns, and worry) was superior to alternative models. The general factor accounted for more than 60% of the variance in EPQ-R-N total scores and was invariant across sex and ethnicity. The 3 group factors varied across ethnicity and sex. We discuss the implications of these findings for conceptualization and assessment of neuroticism using the EPQ-R-N.     

The moral status of a human fetus: a response to Lee.

It is an undeniable empirical fact that a human fetus is a member of the species homo sapiens from the moment of conception. There is thus an important sense in which it is a human being in itself, and not simply part of a pregnant woman's body, despite what defenders of abortion on demand might want us to think. It is also reasonable to suppose that all human beings, and thus human fetuses, are persons, with all that entails, but this is a metaphysical presupposition as opposed to an empirical fact, and is thus contentious. It is argued, however, that this should be of little comfort to the defenders of abortion, because the mere fact that human fetuses have an inherent tendency to become persons is sufficient reason to confer a moral status upon them, which renders abortion morally problematic at best.
