Indirect social influence: Change in judgmental process or anticipatory conformity?

In three experiments, subjects imposed sentence in a criminal case before and after reading the harsh sentence imposed by the trial judge. They then read and imposed sentence in another case. In one experimental condition the subjects anticipated learning the judge's sentence in Case 2; in the other condition they were told not to anticipate learning the judge's sentence. Control subjects made their judgments without ever seeing the judge's sentence. Direct influence was the change in sentences within cases; indirect influence was the difference between initial sentences in Cases 1 and 2. Though direct influence was minimal and not significant, indirect influence was substantial, and was greater in the anticipation than no-anticipation than control conditions, indicating that both modification of the judgmental process and anticipatory conformity were operating. Indirect influence may then reflect a change of either type, depending on a number of methodological and other factors.     

A different form of agraphia: Syntactic writing errors in patients with motor speech and movement disorders

Three patients are described who displayed syntactic writing errors in combination with a motor speech disturbance and impaired motor limb function. Two of the patients had bulbar amyotrophic lateral sclerosis (ALS). Agraphia appeared when verbal communication was no longer possible. Autopsy in one patient disclosed only lesions consistent with ALS. The third patient had palilalia and chorea and, although not aphasic, his written language showed persistent syntactic errors. We hypothesize that the agraphia in these patients occurred because of the combination of disordered feedback from the motor speech apparatus and limbs.     

Extradimensional transfer in the easy-to-hard effect

In three experiments analyzing determinants of the easy-to-hard effect, pigeons acquired a hard discrimination after training on other problems. Intradimensional pretraining resulted in immediate transfer to the hard discrimination. Extradimensional pretraining consistently did not produce immediate transfer but did facilitate learning rate. In Experiment 1, the compounding of cues from an easy extradimentsional discrimination with those from the hard discrimination resulted in the former overshadowing the latter. When different types of extradimensional discriminations were introduced in Experiments 2 and 3, the degree of transfer was not proportional to the similarity in incidental background cues across problems. The findings indicate that in the easy-to-hard effect: (a) intra- and extradimensional mechanisms jointly contribute to the development of stimulus control, (b) intradimensional transfer is more consistent with the gradient-interaction model than the selective attention model, and (c) extradimensional transfer is better accounted for by the construct of general attentiveness rather than by the neutralization of background cues.     

Comparison of student and recruiter values

Value priorities of campus employment recruiters and senior liberal arts students were compared using Rokeach's Value Survey. Three hypotheses were confirmed: (1) Significant differences were found between groups' rankings of values. Students ranked idealistic values high, while recruiters ranked values applicable to business near the top. (2) A greater number of significant differences were found among instrumental values than among terminal values. (3) Regardless of the sex of the applicants, recruiters chose applicants expressing masculine rather than feminine values.     

What's in a title? Personality,job aspirations,and the nontraditional woman

The vocational interests and job aspirations of traditional and nontraditional women in a single work environment were examined in a study of 258 paying-and-receiving tellers. Nontraditionality was operationally defined as choosing the honorific “Ms.” when given the opportunity to do so. Even with a variety of demographic characteristics statistically controlled, nontraditional women scored higher than traditional women on Vocational Preference Inventory Investigative and Enterprising scales. Nontraditional women also aspired to occupations employing a greater percentage of men, but no reliable difference in the prestige level of future aspirations was found. Implications for counseling and the study of career development are discussed.     

Spatial localization in children after changes in position

Five experiments investigated the young child's ability to retrieve a target after a change in the position of the child or the target. In Experiments I–IV 2- to 4-year-old children were rotated 90, 180, 270, or 360° about a stationary square table containing four identical hiding locations at each of the cardinal locations. The children tested performed this task significantly better than chance, but their errors reflected either their response biases in the absence of any information as to the location of the target, or the repetition of a response which had been successful in retrieving the target prior to the change in position. When the children were forced to respond rapidly, these errors increased significantly. In Experiment V a table top was rotated 90, 180, 270, or 360° in front of 3- to 10-year-old children. There were two cue situations. The child saw the rotation, or the child had to infer the rotation. Young children made errors of the types observed in Experiments I–IV. The ability to inhibit these errors increased with age. By 7 years of age performance was virtually perfect when the child could observe the change in position of the hidden object. The ability to infer the positional change developed more slowly and was good but not perfect at 10 years of age.     

Crossed aphasia in an illiterate dextral

An 83 year old illiterate, right-handed woman developed a persistent nonfluent aphasia following a right cerebral infarction (crossed aphasia). Computerized axial tomography localized the lesion to the right posterior frontal lobe.It is suggested that the neural mechanisms involved in learning to read and write may be critical for the complete establishment and maintenance of language dominance in the left hemisphere, and that, in this case, the patient's failure to acquire reading and writing skills altered the normal evolution of language lateralization and resulted in the right hemisphere assuming the dominant role.     

Effects of peer presence on sex-typing of children's play behavior

Effect of peer presence on the sex-typed toy choices of 3- and 4-year-olds was investigated in a repeated measures experimental design. Twenty-six girls and thirty-six boys were tested under three conditions: (a) alone; (b) in the presence of a same-sex peer; and (c) in the presence of an opposite-sex peer. Amount of time spent playing with three feminine- and three masculine-stereotyped toys was recorded. For both boys and girls, play with “sex role-inappropriate” toys was significantly lower in the presence of an opposite-sex peer than in the solitary condition. Across conditions boys exhibited less play with opposite-sex-typed toys than girls. Rate of play with opposite-sex-typed toys increased in successive trials for both sexes. These results indicate that the presence of an opposite-sex peer functions as a discriminative stimulus for avoidance of “sex role-inappropriate” play in preschoolers and suggests that preschoolers may have a history of differential reinforcement for sex-typed play in the presence of peers.     

Compound conditioning: Elimination of the blocking effect

Prior conditioning employing one element of a compound stimulus as the CS blocked the acquisition of a Conditioned Emotional Response (CER) to the second element of a simultaneous compound stimulus that was subsequently used as the CS in further conditioning trials. Presentation of a brief “surprise” stimulus 3 or 5 sec after the occurrence of the US during the compound trials eliminated the blocking effect.
