Alcohol consumption by college women following exposure to unsolvable problems: Learned helplessness or stress induced drinking?

Three experiments were intended to examine the relationship between alcohol, depression and learned helplessness. In Study I, more female undergraduate heavy drinkers than light drinkers were found to have critically elevated scores on a depression index. A sex difference in the relationship between drinking and depression is suggested since male depressives were equally distributed among drinking categories. In Studies II and III, female undergraduates were given unsolvable problems in a learned helplessness paradigm. Relative to controls these subjects reported increased depressive and hostile affect and drank more beer in a taste rating task. However, we failed to find deficits in anagram solution with those subjects given the learned helplessness manipulation. Specific questions are raised regarding the boundary conditions of learned helplessness while implications bearing on stress-related alcohol consumption are discussed.     

TRANSITIONS IN CHILDREN'S ROLES AND CAPABILITIES*

Stage theories and empirical studies have concentrated on a few periods of childhood (e.g., age 5 to 7 years) as important times of transition. On the basis of ethnographic suggestions that the age period 8 to 10 years also involves interesting changes, the authors carried out a search of published empirical studies for findings of transitions in capabilities at 8 to 10 years. An annotated bibliography is provided summarizing the studies found in a 5-year period in three journals. The authors discuss possibilities for characterizing the transition at age 8 to 10, as well as how such a transition meshes with the concept of stage.     

A further analysis of the affective meanings associated with male and female sex-trait stereotypes

This study was concerned with the qualitative differences in the male and female sex-trait stereotypes. Previous research employing the item pool of the Adjective Check List (ACL) had indicated no relationship between the stereotype loading of the adjectives and their favorability ratings. In the present study, university students rated the ACL items for strength and activity, and these ratings were used to demonstrate that the male stereotype was appreciably stronger and more active than the female stereotype. It was found that the strength ratings were highly correlated with both activity and favorability ratings which were, themselves, unrelated. It was concluded that the principal qualitative difference between the stereotypes lay in the connotations of activity and passivity associated, respectively, with the male and female stereotype traits, and that any assertion of greater social desirability for the male stereotype was based on its greater activity and not, as is often supposed, on its greater favorability.     

Free classification: Element-level and subgroup-level similarity

Subjects classified sets of multidimensional stimuli into two groups in any way they wished. The sets were composed of 6 or 12 stimuli: 2 or 4 instances of 3 different stimuli (e.g., 2 blue circles, 2 green circles, 2 red circles). There were striking individual differences in the preferred classification. Some subjects maximized the similarity between subgroups by matching the composition of the subgroups--one instance of each stimulus was placed in each group. The other subjects maximized the similarity among stimuli within each subgroup by placing similar stimuli in each group (the blues and greens in one group, the reds in the other). The nature of the stimuli as well as the relationships among the three stimuli had little effect on classification. In this case, cognitive styles specific to individuals but general across diverse dimensions and stimulus sets determined classification.     

A set-theoretic random utility model of choice behavior

A random utility model of choice was developed by combining the basic ideas of the well-known theories of Thurstone and Restle. The new model has exactly the same number of free parameters as Tversky's Elimination-by-Aspects model. Furthermore, both models were found to fit, with equal accuracy, the data reported by Rumelhart and Greeno, and Tversky. It was concluded that although the two theories are not identical, they may be difficult to discriminate empirically.     

Overt expression of experimenter expectancies,interaction with subject expectancies,and performance on a psychomotor task

Subsequent to success or failure experience, 48 subjects attempted a psychomotor task in order to escape or avoid an aversive stimulus (tone). Their attempts at solving the task over 24 trials were made in the presence of subject-experimenters each of whom had expectancies instilled regarding the solution to the task. The job of the subject-experimenters was to “offer information” on every third trials as the subjects attempted to solve the task. It was hypothesized that the expectancies of the subject-experimenters would be communicated to the subjects via periodic comments, that these expectancies would differentially affect the subjects' performance on the task, and that prior experience on a similar task would differentially affect subjects' performances on the task. The results demonstrated that the expectancies instilled in the subject-experimenters were communicated and influenced the performances of subjects as predicted. It appears that consistency with respect to the expectancies communicated played a major role in producing significant effects. Prior experience failed to produce significant differences on task performance, a finding conflicting with that of D.S. Hiroto (Journal of Experimental Psychology, 1974, 102, 187–193). The results are discussed from the perspective of using the overt, explicit communication of expectancies as a means for exploring the illusive phenomenon of the experimenter expectancy effect.
