A parametric study of learned helplessness in humans

In two experiments designed to assess the effect of varying amounts of exposure to noncontingency training, it was discovered that performance decrements could be produced after relatively brief training and again after extended training. Between these conditions was a period of recovery during which no performance deficits were evident. There was also a tendency for individual differences in motivation to moderate deficits following brief but not extended training. A four-stage model is proposed to account for these results. In response to uncontrollable outcomes, individuals are said to pass through a phase of no effect, followed by temporary helplessness, recovery, and final helplessness. The model also proposes that motivational differences and perceptions of noncontingency exert independent and opposing influences on learned helplessness deficits.     

Thinking about the past,present, and future: Time perspective and self-esteem in adolescents,young adults,middle-aged adults,and older adults

We examined time perspective and self-esteem in adolescents, young adults, middle-aged adults, and older adults. Time perspective was measured with scales that assess relative orientations and relationships among the past, present, and future. Age effects were examined with standard analytic strategies to determine categorical differences between age groups and with new statistical techniques designed to show continuous age patterns. Findings indicated that (1) thinking about the future was greatest for adolescents and young adults and lowest for middle-aged and older adults, and thinking about the present increased across ages; (2) fewer adolescents and middle-aged participants perceived that the time periods were interrelated compared to younger and older adults; and (3) across ages, a greater emphasis towards the past compared to other time periods was associated with lower self-esteem, whereas emphasizing the present and the future jointly was associated with higher self-esteem.

Long-term influence of divorce and single parenting on adolescent family- and work-related values, behaviors, and aspirations.

Following a summary of the relevant divorce research, this article examines possible long-term influences of both divorce and living with a single mother on the development of adolescents' values and plans. We examine how divorce affects children both directly and indirectly through its impact on the mother's resources, attitudes, and socialization goals. Particular focus is placed on those aspects of family interaction that impact on identity formation as it is linked to educational and occupational goals and to gender-role related behaviors associated with marriage, family, and job plans. Possible benefits as well as potential costs of living with a single mother are discussed.     

The Role of Reproductive Strategies in Academic Attainment

Since there is a tradeoff between prolongedformal education and early reproduction, education canbe construed as a long-term reproductive tactic. Thisreproductive strategies approach was tested by looking at relationships between sociosexuality (SOI)and parental investment (parental income, number ofsiblings, parental divorce, number of step siblings,birth intervals, birth order, closeness to parents) and GPA of 139 White students at a privatecollege. Parental investment was reduced to threefactors (Family Composition, Family Security, andMarital Instability), the last of which was negativelycorrelated with GPA and positively correlated with SOI.SOI was a much stronger (negative) predictor of GPA inwomen, but not men, than ACT was. Results support thereproductive strategies approach and imply that prediction of academic difficulty (and genderdifferences therein) must confront reproductiveissues.     

On Post-Heideggerean Difference: Derrida and Deleuze

This paper takes up the Heideggerean question of difference. I argue that while Heidegger raises this question, his response to the question remains ambiguous and that this ambiguity pivots around the question of time. The bulk of the paper then looks at how Derrida and Deleuze respectively attempt to advance beyond Heidegger's ambiguity regarding the questions of difference and time. Derrida is able to demonstrate the manner in which time—as delay—is constitutive of any attempt to think difference. I argue, however, that his innovative articulation of “différance” maintains an extrinsic rather than intrinsic relation to difference in-itself. To achieve an intrinsic relation, it is necessary to turn to the work of Deleuze, particularly to his discussion of “nonsense” and “singularity.”     

Self-Perceptions of Comparative Power and Worth in Three Generational Families

This study focused on the extent to which self-perceptions of power and worth differed across members of three-generational families as they compared themselves with other family members. It was hypothesized that self evaluations of worth would show more stability than self evaluations of power in such comparisons. There was support for this hypothesis. Differences regarding self evaluations of power according to gender and generation were also examined. The rank order, from lowest to highest, of perceived comparative power was: female adolescent grandchildren, grandmothers, mothers, male adolescent grandchildren, grandfathers, and fathers. Implications of findings for family therapists are described.
