Three accounts of the learned helplessness effect

Two experiments tested predictions drawn from test anxiety theory, learned helplessness theory, and Wortman and Brehm's (1975) integration of helplessness and reactance theories. Experiment 1 demonstrated that performance deficits predicted by learned helplessness do not rely on experimenter-induced failure. It also showed such deficits to be unrelated either to negative affect following exposure to pretreatment or to causal attributions about pretreatment task performance. Experiment 2 showed that experience of uncontrollability need not result in impaired performance, because failure on an unimportant task did not produce the deficits predicted by learned helplessness theory. This result provides qualified support for the integrative model. Finally, because the subjective measures used in Experiment 2 were not consistent with performance measures, the reliability of self-reports is questioned.     

Learned helplessness as conditioned inattention to the target stimulus

Learned helplessness theory explains the impaired performance that follows exposure to uncontrollable outcomes by assuming learned expectation of response-outcome independence that is transferred between tasks. Recent evidence has shown that introducing a second neutral stimulus, contingent on the offset of the uncontrollable stimulus, removes the subsequent interference. This finding has been claimed to support the view that the interference is a result of conditioned inattention rather than of the expectation of response-outcome independence. These conflicting explanations were examined in a series of four experiments that varied induction procedures (passive exposure or inescapability) and stimulus quality (aversive or nonaversive). All four experiments found the predicted interference, but only one, in which passive exposure was combined with an aversive stimulus, obtained results supporting the conditioned inattention hypothesis. We conclude that learned helplessness probably involves more than a single mechanism and that the passive exposure procedure may not be appropriate for demonstrating genuine helplessness deficits.     

Peripheral vision monitor: Presenting displays at known positions in the visual periphery

The peripheral vision monitor is an inexpensive device that ensures that visual stimuli can be successfully projected to a given extrafoveal location. The apparatus extinguishes the display lighting system when the observer attempts to view a region intended to be viewed only in peripheral vision, reinstating the illumination when that region is again in the peripheral field. This is achieved by focusing a small spot of light on the scleral-corneal boundary of the observer’s eye and detecting the reflected light with a photocell and circuit. Illumination changes produced at the photocell are used to trigger the display lighting.     

Women's Dress Fashions as a Function of Reproductive Strategy

Despite many speculations, there is no well-supported explanation for cycles of fashion in.women's dress and scholars cannot agree whether fashions reflect societal changes. Generalizing from cycles of bodily attractiveness for women, it was hypothesized that dress styles are reflective of reproductive economics. Using data from three studies of dress fashion extending from 1885-1976, the prediction was tested thatshortskirts (signaling sexual accessibility) would be correlated with low sex ratios (indicating limited marital opportunity for women), with increased economic opportunities for women and with marital instability. Predictions for narrowwaists and low necklines (which signal reproductive value) were opposite. These predictions received strong support indicating that dress styles, like standards of bodily attractiveness may be partly determined by marital economics.
