Intelligence and the Frontal Lobe: The Organization of Goal-Directed Behavior

Basic to the study of individual differences is the concept of “general intelligence” or Spearman'sg.In this article we suggest thatgis largely a reflection of the control functions of the frontal lobe. A series of experiments investigates a phenomenon we callgoal neglect:disregard of a task requirement even though it has been understood and remembered. Subjectively it is as though the neglected requirement “slips the subject's mind.” Previously described in frontal patients, we show that goal neglect can also be seen in some members of the normal population. In line with conventional distinctions between controlled and automatic processing, eliciting conditions for goal neglect include novelty, weak error feedback, and multiple concurrent task requirements. Under these conditions neglect is linked closely togand extremely common after frontal lesions. Following many other models, we suggest that behavior in any task is structured by a set of action constraints or requirements, derived in part from verbal instructions and specified at multiple levels of abstraction. A frontal process of constraint or requirement activation is fundamental to Spearman'sg.     

Gender role typing,the superwoman ideal,and the potential for eating disorders

The interactive effects of gender role typing and adherence to a superwoman ideal (desiring to excel in many diverse roles) on the potential for disordered eating were examined among a nonclinical sample of women. Results indicated that both masculine and feminine gender-typed women who strongly adhered to a superwoman ideal were at greater risk for eating disorders than androgynous superwomen. In contrast, androgynous superwomen had relatively low potential for disordered eating and appeared comparable to women who, regardless of gender typing, rejected the superwoman ideal. Women undifferentiated with regard to gender type, whether superwomen or not, also had reduced potential for disordered eating. Findings are discussed with regard to gender role socialization and expectations, and the implications for mediating the potential for eating disorders are considered.     

Fertility,sex role attitudes,and labor force participation

Data from the 1970 National Fertility Study were used to investigate the relationships between sex role attitudes and the childbearing and labor force participation of women. While several relevant dimensions of sex role attitudes were identified, it was found that the most crucial aspect for working and fertility was the extent to which the woman identified the female role as that of housewife and homemaker. Those having traditional definitions concerning this role were less likely to be working, and had fewer plans to work in the future. In addition, as expected, women with traditional sex role definitions had more children than others. While the orientation of the woman toward the home was the primary correlate of work and fertility, those who felt that women had little control over their lives had higher fertility than others—a relationship which could be explained partially, but not entirely, in terms of unplanned childbearing.     

You can't always get what you want: educational attainment, agency, and choice

Using educational attainment to indicate socioeconomic status, the authors examined models of agency and effects of choice among European American adults of different educational backgrounds in 3 studies. Whereas college-educated (BA) participants and their preferred cultural products (i.e., rock music lyrics) emphasized expressing uniqueness, controlling environments, and influencing others, less educated (HS) participants and their preferred cultural products (i.e., country music lyrics) emphasized maintaining integrity, adjusting selves, and resisting influence. Reflecting these models of agency, HS and BA participants differently responded to choice in dissonance and reactance paradigms: BA participants liked chosen objects more than unchosen objects, but choice did not affect HS participants' preferences. Results suggest that HS and BA models of agency qualitatively differ, despite overlap between HS and BA worlds.     

Explicit mechanisms do not account for implicit localization and identification of change: An empirical reply to Mitroff et al. (2002)

Several recent findings support the notion that changes in the environment can be implicitly represented by the visual system. S. R. Mitroff, D. J. Simons, and S. L. Franconeri (see record 2002-15293-003) challenged this view and proposed alternative interpretations based on explicit strategies. Across 4 experiments, the current study finds no empirical support for such alternative proposals. Experiment 1 shows that subjects do not rely on unchanged items when locating an unaware change. Experiments 2 and 3 show that unaware changes affect performance even when they occur at an unpredictable location. Experiment 4 shows that the unaware congruency effect does not depend simply on the pattern of the final display. The authors point to converging evidence from other methodologies and highlight several weaknesses in Mitroff et al's theoretical arguments. It is concluded here that implicit representation of change provides the most parsimonious explanation for both past and present findings. ((c) 2003 APA, all rights reserved)
