Same-sex patterns and sex differences in the trust-value basis of children's friendship

Thirty-six children in fourth grade were required (a) to report the secret-sharing, secret-keeping, promise-making, and promise-keeping behaviors of classroom peers; and (b) to judge those classmates on trust and friendship. Teachers provided observations of the children's friendship interaction. Same-sex patterns were found in observed friendship, friendship ratings, trust, secrets shared, proportion of secrets kept, and promises made. These were less frequent/lower for opposite-sex peers than for same-sex peers. As expected, males tended to share fewer secrets with same-sex peers than did females. The expected associations were found among proportion of secrets kept, proportion of promises kept, trust, and rated or observed friendship in females but with one exception in males. The findings supported the conclusion that same-sex friendship patterns are maintained by same-sex trust patterns through (a) infrequent secret sharing with opposite-sex peers and (b) the perception that opposite-sex peers break secrets more frequently than same-sex peers. The findings also supported the conclusion that there are some sex differences in the intimacy/trust basis of friendship.     

On the nature of neutral primes in a lexical decision task

Summary Research concerned with semantic priming has used a neutral prime as a benchmark for measuring the amount of facilitation for related targets and the amount of inhibition for unrelated targets. Recently, de Groot, Thomassen, and Hudson (1982) have reported that lexical decisions to targets are faster when preceded by the neutral prime BLANK as compared to a neutral prime consisting of a string of X's. Additionally, Antos (1979) has reported that an X neutral prime induces an inhibitory effect when the stimulus-onset-asynchrony (SOA) is short. The present experiment manipulated class of neutral prime, SOA, and practice. The results failed to support the observation by Antos. However, the results did support the finding by de Groot et al. at shorter SOA's (200 and 550 ms). At a longer (1000 ms) SOA the effect of the two neutral primes as well as the effect of the unrelated primes were equivalent. Practice had no differential effect on either of the neutral primes as compared to the unrelated priming conditions. These results were interpreted to mean that the difference between the two neutral primes at a brief SOA were perceptual in origin and that an unrelated word prime is neutral with respect to the target in the absence of strategic priming effects.     

The relation between syllable number and visual complexity in the acquisition of word meanings

Four experiments were conducted to explore the correlation between syllable number and visual complexity in the acquisition of novel words. In the first experiment, adult English speakers invented nonsense words as names for random polygons differing in visual complexity. Visually simple polygons received names containing fewer syllables than visually complex polygons did. In addition, analyses of English word-object pairings indicated that a significant correlation between syllable number and visual complexity exists in the English lexicon. In Experiments 2 and 3, adult English speakers matched monosyllabic novel words more often than trisyllabic novel words with visually simple objects, whereas trisyllabic matches were more common for visually complex objects. Experiment 4 replicated these findings with children, indicating that the assumption of a correlation between word and visual complexity exists during the period of intense vocabulary growth. Although the actual correlation between syllable number and visual complexity is small, other posited constraints on word meaning are also limited in strength. However, an increasing number of small, language-specific word-meaning correlations are being uncovered. Given the documented ability of speakers to detect and use these subtle correlations, we argue that a more fruitful approach to word-meaning acquisition would forgo the search for a few broad, powerful word-meaning constraints, and we attempt to uncover individually weak, but perhaps jointly powerful word-meaning correspondences.     

Order and serial position effects in response time with multiple-item probe recognition

We examined the order effect in item-recognition response time, that is, differences in response time for multiple-item probes containing items in the same or in the reverse order as those in the memory set. Experiment 1 used the response condition in which only one item must be positive for a positive response, Experiment 2 used homogeneous probes in which all the items are either positive or negative, and Experiment 3 used the condition in which all the items must be positive. Of particular interest were the serial position variations in order effects for probes containing items that were adjacent in the memory set. We previously found that such effects are an indication of subjective grouping of the memory set and the matching of the probe with these subgroups. The order effect in the one-positive condition was only weak in most cases, but it was strong with homogeneous probes when the memory set was objectively grouped or was ungrouped but with a constant set size. There were also strong order effects in the all-positive condition for probes with items that were nonadjacent in the memory set. Our results are interpreted in terms of a parallel match process based on a distribution over position of items in subjective or objective groups. We account for the origin of the distribution-over-position process in terms of multiple representations of the grouped memory sets. The model assumes that each subgroup is represented in memory several, and perhaps very many, times and that considerable error in item positioning can occur over the multiple representations of any group.     

Guidance for Submission: Social Control and Guidance in Schools for Black Pupils in South Africa

The use of a school guidance service to transmit the economic and cultural interests of the ruling group(s) in a country is explored through the case-study of guidance in the Republic of South Africa, and in particular the introduction of guidance as a subject in Black schools in 1981. An analysis of the syllabus for guidance in Black schools reveals a social-control strategy on the part of the power group, which is different to that used within the White guidance service. Whereas the White service emphasises cultural interests, the Black-school syllabus stresses the economic interests of the ruling group. Each service, however, reflects the tension between economic and cultural interests, and the guidance situation in South Africa demonstrates the complex relationship between these interests, as well as that between group power relations and the nature of guidance services. The case-study also comments upon the relationship between the power of the ruling group in South Africa and the degree to which its economic and cultural interests are made explicit in the syllabus of its guidance services.     

Oculomotor adjustments and size constancy

The effect on matched size of the oculomotor adjustments was determined by stimulation and relaxation of accommodation and convergence by means of spherical lenses. The normal coupling between accommodation and convergence was maintained by introducing the amount of convergence appropriate to the lens power and each S’s interpupillary distance. Data indicate that the oculomotor adjustments are adequate to account for size constancy up to approximately 1 m, beyond which their effect progressively decreases. The actual accommodation in force was assessed by means of the laser scintillation technique. It was determined that the magnitude of accommodation responds accurately to the spherical lens introduced up to about 1 m observation distance, beyond which underaccommodation was noted. Examination of the matched size as a function of the actual accommodation distance reveals a very close correspondence to the size constancy prediction up to about 1 m.     

Attributes of successful approaches to weight loss and control

Most weight loss treatments result in only temporary losses, followed by slow regain. This paper examines those factors that are correlated with the most favorable results in terms of loss and maintenance of loss. Weight loss is positively related to self-monitoring, goal setting, social support, and length of treatment. Maintenance of weight loss is correlated with regular physical activity, self-monitoring, and continued contact with therapists. Regain is associated with inconsistent and restrictive dieting, life stress, negative coping style, and emotional or binge eating patterns. The implications drawn from these findings are (a) normalize eating patterns, (b) emphasize exercise, (c) ensure social support, (d) set realistic goal weights, (e) focus on health rather than appearance, (f) focus on self-esteem, and (g) target binge eating.
