The influence of functional social support on executive functioning in middle-aged African Americans

Social support has a positive influence on cognitive functioning and buffers cognitive decline in older adults. This study examined the relations between social support and executive functioning in middle-aged adults. A community-based sample of African Americans completed the Interpersonal Support Evaluation List, a measure of functions of social support, and two measures of executive functioning, the Stroop Color and Word Test and the Wisconsin Card Sorting Test (WCST). Hierarchical regression analyses were used to explore the hypothesis that different facets of perceived social support influence performance on measures of executive functioning. After controlling for age, gender, and education, social support facets including belonging support, self-esteem support, appraisal support, and tangible support were significant predictors of Stroop performance. In addition, tangible support significantly predicted WCST performance. These findings add to previous literature on social support and cognition; however, findings for middle-aged adults are unique and suggest that social support has a positive influence on some executive functions in African Americans prior to old age.     

Psychometric properties and dimensional structure of the Spanish adaptation of the Coping Inventory for Competitive Sport

The purpose of this study was to adapt and validate a Coping Inventory for Competitive Sport (ISCCS), establishing its psychometric properties and its dimensional structure. Participants were 306 athletes from different sports, aged between 14 and 28 years (45.7% males and 54.3% females), who completed the ISCSS along with other measures of constructs theoretically related to coping. Factor analysis identified eight factors that merged in three high-order dimensions representing task-oriented coping, emotion-oriented coping and disengagement-oriented coping. The factors showed appropriate reliability (Cronbach alpha and factor correlations), convergent validity (correlations with COPE Inventory scales) and concurrent validity (correlations with CSAI-2 and PANAS scales). It is concluded that the Spanish version of the ISCCS has proved to be a valid and reliable instrument to identify and assess competitive coping strategies, allowing psychological intervention to improve athletes' performance.     

Modest meta‐philosophical skepticism

Intractable disagreement among philosophers is ubiquitous. An implication of such disagreement is that many philosophers hold false philosophical beliefs (i.e. at most only one party to a dispute can be right). Suppose that we distribute philosophers along a spectrum arranged from philosophers with mostly true philosophical beliefs on one end (high‐reliability), to those with mostly false philosophical beliefs on the other (low‐reliability), and everyone else somewhere in‐between (call this is the reliability spectrum). It is hard to see how philosophers could accurately locate themselves on the reliability spectrum; they are prima facie as well positioned as their peers with respect to philosophical matters (call this the placement problem). In this paper, I argue that the reliability spectrum and placement problem lend support to modest meta‐philosophical skepticism: we have a pro tanto (but not an all‐things‐considered) reason to withhold ascent to philosophical claims.     

Tactical skills and ball speed during a field simulation of penalty kick strategies in soccer

This study investigates the efficacy of intermediate penalty kickers by comparing the effect of applying an automated WiFi system on the field of play to simulate a strategy that takes account of goalkeeper action (dependent) with another for which goalkeeper strategy is irrelevant (independent). Intermediate penalty kickers (n=12) took a pretreatment test of 32 kicks in a "real-play" situation with intermediate goalkeepers (n=3). Two groups of kickers underwent 11 treatment sessions using different strategies and then were administered a posttreatment test. The variables measured were the number of goals scored, whether the direction of the shot was the same or different from the direction of the goalkeeper's move (DDG), ball speed, and the duration of the kicking movement. Data suggested the goalkeepers had a greater capacity to identify advance cues when faced with independent strategy kickers and that dependent strategy kickers achieved lower ball speeds.     

Patterns of comprehension performance in agrammatic Broca's aphasia: a test of the Trace Deletion Hypothesis

We tested the core prediction of the Trace Deletion Hypothesis (TDH) of agrammatic Broca's aphasia, which contends that such patients' comprehension performance is normal for active reversible sentences but at chance level for passive reversible sentences. We analyzed the comprehension performance of 38 Italian Broca's aphasics with verified damage to Broca's area, who completed sentence-to-picture matching tasks using active and passive reversible sentences as stimuli. The results failed to confirm the predictions made by TDH: only a small minority (15%) performed at chance on passive sentences and better than chance on active sentences. Furthermore, the distribution of the 38 subjects' performance on passive sentences differed from that predicted by the TDH since many more subjects performed at better-than-chance levels than expected. We discuss the implication of these results for claims about the distribution of language processing mechanisms in the brain.     

Does Respect for Embryos Entail Respect for Gametes?

Respect for human embryos is often defended on the basis of the potentiality argument: embryos deserve respect because they already possess potentially the features that in adults are fully actualized. Opponents of this argument challenge it by claiming that if embryos should be respected because they are potentially adults, then gametes should be respected because they are potentially embryos. This article rejects this reductio ad absurdum argument by showing that there are two different types of potentiality involved so that the transitivity of potentiality does not hold up in this case. Respect for embryos does not logically entail respect for gametes.     

The selection of grammatical features in word production: the case of plural nouns in German

Two experiments investigate the effect of number congruency using picture-word interference. Native German participants were required to name pictures of single objects (Nase 'nose') or two instances of the same object (Nasen 'noses') while ignoring simultaneously presented distractor words. Distractor words either had the same number or were different in number. In addition, the type of plural formation (same or different inflectional plural suffix) and the semantic relationship (same or different semantic category) between target and distractor were varied in Experiments 1 and 2. Results showed no effect of number congruency in either experiment. Furthermore, the type of inflectional suffix did not exert an influence on naming latencies in Experiment 1, but semantic relationship led to a significant interference effect in Experiment 2. The results indicate that selection of the number feature diacritic in noun production is not a competitive process. The implications of the results for models of lexical access are discussed.     

The absence of a gender congruency effect in romance languages: a matter of stimulus onset asynchrony?

Using the picture-word interference paradigm, H. Schriefers and E. Teruel (2000) found that in German the grammatical gender of the distractor word affects the production of phrases composed of article+picture name: Latencies were longer for picture-word pairs of different genders. However, the effect was found only at positive stimulus onset asynchronies (SOAs; i.e., when pictures were presented 75 or 150 ms earlier than word distractors). This gender congruency effect is not obtained in Romance languages. The present article examines whether in these languages, as in German, the effect appears at positive SOAs. No effect was observed in Italian and Spanish at positive SOAs. An account is proposed to explain why the gender congruency effect is obtained in Germanic (Dutch and German) but not in Romance languages.     

Displacement activities as a behavioral measure of stress in nonhuman primates and human subjects

Traditionally, research on human stress has relied mostly on physiological and psychological measures with a relatively minor emphasis on the behavioral aspects of the phenomenon. Such an approach makes it difficult to develop valid animal models of the human stress syndrome. A promising approach to the study of the behavioral correlates of stress is to analyze those behavior patterns that ethologists have named displacement activities and that, in primates, consist mostly of self-directed behaviors. In both nonhuman primates and human subjects, displacement behavior appears in situations characterized by social tension and is likely to reflect increased autonomic arousal. Pharmacological studies of nonhuman primates have shown that the frequency of occurrence of displacement behavior is increased by anxiogenic compounds and decreased by anxiolytic drugs. Ethological studies of healthy persons and psychiatric patients during interviews have found that increased displacement behavior not only correlates with a subjective feeling state of anxiety and negative affect but also gives more veridical information about the subject's emotional state than verbal statements and facial expression. The measurement of displacement activities may be a useful complement to the physiological and psychological studies aimed at analyzing the correlates and consequences of stress.
