Sex differences on use of associative and dissociative cognitive strategies among male and female athletes

This study assessed whether men and women differed in using associative and dissociative cognitive strategies during athletic performance. Athletes (31 men, M age = 23.2 yr., SD = 3.9 and 29 women, M age = 22.9 yr., SD = 4.3) who practiced endurance activities (running, swimming, and cycling) were considered high-level performers because they participated in national or international competition. The athletes were interviewed, and Schomer's 1986 method of measurement was used to evaluate and quantify two cognitive strategies. Most specifically, categories of association concerned the way the athlete paid close attention to bodily signals, and categories of dissociation described how the athlete shunned sensory inputs. Analysis of variance and the t test showed that women tend to be more dissociative than men and men more associative than women. The results suggest that pain perception in these sports may be a function of sex.     

Simone de Beauvoir and the Graying of American Feminism

Simone de Beauvoir's study on age and aging can be read as an example of feminist scholarship presenting the contradictions and the ambivalence inherent in any topic dealing with women and society. Beauvoir's work both applauded and criticized by feminist scholars offers an important document for addressing the double discrimination based on gender and age, and has been influential in defining a feminist approach to the discussion of gender and age. With the graying of American feminists in the 1990s, age became a concern and Beauvoir's contribution to the area of age studies received recognition as an early contribution to the humanist exploration of the topic of aging. This article surveys interpretations of Beauvoir's work on aging by literary critics, feminist historians, and a gerontologist.     

Functional equivalence of spatial representations derived from vision and language: evidence from allocentric judgments

Past research (e.g., J. M. Loomis, Y. Lippa, R. L. Klatzky, & R. G. Golledge, 2002) has indicated that spatial representations derived from spatial language can function equivalently to those derived from perception. The authors tested functional equivalence for reporting spatial relations that were not explicitly stated during learning. Participants learned a spatial layout by visual perception or spatial language and then made allocentric direction and distance judgments. Experiments 1 and 2 indicated allocentric relations could be accurately reported in all modalities, but visually perceived layouts, tested with or without vision, produced faster and less variable directional responses than language. In Experiment 3, when participants were forced to create a spatial image during learning (by spatially updating during a backward translation), functional equivalence of spatial language and visual perception was demonstrated by patterns of latency, systematic error, and variability.     

Use of cognitive versus perceptual heading during imagined locomotion depends on the response mode

Three experiments investigated whether the systematic errors previously observed in a triangle-completion task were caused by failures to form and update a cognitive heading or by use of perceived heading (even though an updated cognitive heading was available) during the response. These errors were replicated when participants indicated the origin of triangular paths they had imagined walking by turning their bodies toward the origin, but not when they responded verbally. The results indicate that participants are capable of updating their cognitive heading using imagined movements and suggest that the systematic errors previously observed were a result of the strong attachment of responses such as turns to a perceptual representation of the physical body.     

Firstborn preference and attitudes toward using sex selection technology

The authors investigated sex preferences for firstborn children and (a) pro- technology attitudes and willingness to use sex selection technology (SST) and (b) social conformity. College students (N = 469; 239 women, 230 men) answered demographic questions and questions on technology usage and personal preferences and completed a measure of conformity. Findings revealed a significant overall preference for firstborn males, a specific preference of potential SST users for firstborn sons, and a greater willingness of African American students, compared with White students, to use SST. No correlation was found between conformity and potential SST use. Logistic regression results suggested that protechnology attitudes may be predictive of firstborn preferences. Implications of the findings are discussed in relation to gender equality and population sex ratios.     

Grammatical class effects in brain-damaged patients: functional locus of noun and verb deficit

Two patients are described with grammatical class dissociation: CG, a semantic-dementia patient who presented a disproportionate impairment of nouns compared to verbs; SA, a patient with a left parietal lesion who presented impaired sentence production and a disproportionate deficit for verbs compared to nouns. The results are discussed within the current models on semantic memory and lexical access.     

Ongoing postdivorce conflict and child disturbance

This paper reports on the disturbed behavior of children who are subject to entrenched parental disputes over their custody and care after separation and divorce. The 56 children who varied in racial and socioeconomic origin were 4 to 12 years old at entry into the study. They were assessed at two points: at the time of the custody dispute and 2.5 years later. The extent of the child's involvement in the dispute and the amount of role reversal between parent and child predicted total behavior problems and aggression at the time of the legal dispute. These same factors, together with the rate of verbal and physical aggression between parents, predicted total behavior problems, depression, withdrawn/uncommunicative behavior, somatic complaints, and aggression at the 2-year follows-up. There were no main effects for sex and age. However, at the 2-year mark, girls in high-conflict families were more depressed and withdrawn, and older children in high-conflict situations had more somatic complaints and were more aggressive. The findings are considered in the light of a number of etiological mechanisms by which parental conflict affects children. Funds for the clinical work were provided by the Zellerbach Family Fund and the San Francisco Foundation the Van Loben Sels Foundation, and the Morris Stulsaft Foundation.

The recognition and categorization of upright and inverted emotional expressions by 7-month-old infants

Upright and inverted faces were used to determine whether 7-month-old infants discriminate emotional expressions on the basis of affectively relevant information. In Experiment 1, infants recognized the similarity of happy faces over changing identities and discriminated this expression from fear and anger when the stimuli were presented upright, but not when they were inverted. In Experiment 2, infants were able to discriminate happiness from fear and anger posed by a single model, regardless of the orientation of the stimuli. From these studies it was suggested that categorizing emotional expressions depends upon attending to affectively relevant, orientation-specific information, whereas the discrimination of emotional expressions can be done on a featural basis, something that remains invariant regardless of the orientation of the stimuli. In Experiment 3, infants discriminated toothy happiness posed by several models from nontoothy happiness and nontoothy anger when the stimuli were presented upright and inverted. Thus, when salient features were available, the infants based their discriminations on perceptual aspects rather than on conceptual aspects such as categories of emotions.
