Gender stereotyping in young children: Evidence to support a concept-learning approach

Two studies on early gender stereotyping based on a concept-learning approach were conducted. With the use of a forced choice format, study 1 found that both 2 1/2 and 3 1/2-year-old children showed significant and equal stereotyping of both gender-labeled infants and animals. These findings suggest both early learning and generalization of gender stereotypes. In study 2, although 5-year-olds stereotyped more strongly than 3-year-olds, both groups stereotyped others significantly more than themselves. When attributing traits to themselves, children chose the more socially desirable rather than the gender-traditional attributes. These findings are discussed in terms of the acquisition of gender stereotypes as a process distinct from the necessity for related self-schemas.The authors would like to express their appreciation to Pam Newman, Laurie MacGavin, Rebeccah Warren, Sheryl Wilson, Gail McCollum, and Cheryl Hessen for their invaluable assistance in running subjects for these studies.     

Paradoxical intervention using a polarization model of cotherapy in the treatment of elective mutism: A case study

A case history is presented of a four and-a-half year-old electively mute child who was successfully treated by the authors. The treatment approach involved paradoxical interventions in the context of a polarization model of cotherapy in combination with behavioral techniques in a family therapy framework.     

Suicide and the contemporary woman: Are male and female suicide rates converging?

Nationwide statistics on White suicide rates for the years 1960–1978 are examined to assess whether the suicide rates of women are increasing relative to those of men. This is accomplished by calculating for the total population and for several age groupings the sex differential (SD), which is defined as the percentage of suicides which are female after adjustments are made for the sex distribution in the population. The data reveal that the SD narrowed from 1960–1967, held steady from 1968–1972, and then widened slightly from 1973–1978. The most important aspects of these trends are that (a) the narrowing of the SD is due more to declining suicide rates among older (over-40) males than to increasing female suicide rates, and (b) the narrowing of the SD and the small increases in female suicide rates occurred prior to 1970 and thus were earlier than would be expected on the basis of changing sex-role expectations. Post hoc explanations of these patterns refer to methodological factors and to changes in social integration resulting from a variety of sociohistorical factors.     

The extent of processing of noise elements during selective encoding from visual displays

Circular visual displays of 12 elements, consisting of A, H, M, and U, were presented to S. She responded with a lever movement in one direction if a given letter designated by a bar indicator was a member of the set A-U and in the opposite direction if it was from the other set. The principal experimental variables were the SOA by which the indicator preceded the display and whether the target letter was flanked by letters of the same or opposite set. The results indicated that the interference produced by noise letters is primarily on the response as opposed to the processing side. Also, there is a limit to the precision of selective attention in the visual field. The interference of opposite-set letters was inversely proportional to their distance from the target.     

Selective encoding from multielement visual displays

When a multiletter display is preceded by a bar designating one of the letters for report, reaction time (RT) to voice the indicated letter decreases. Previous research had indicated that the efficiency of this selective mechanism decreases as the number of display elements increases. Two experiments were conducted to determine whether the effect of display size could be eliminated when the indicator precedes the display at long intervals. Results indicated that the display size effect was maintained. The results could not be attributed to eye movements, but were interpreted in terms of a central encoding mechanism that is limited in its precision of localization and exclusion.     

Isolation-induced aggression in newly hatched ducklings.

Newly hatched Khaki Campbell ducklings (Anas platyrhynchos domesticus) were initially housed in pairs and subsequently transferred to isolated housing conditions. Subjects living with another bird displayed filial behavior and little aggression upon encountering another duckling in a test arena. In contrast, ducklings housed in isolation exhibited aggressive pecking in addition to filial behavior when another duckling was subsequently encountered. In Experiment 2, ducklings were housed with an imprinting object (i.e., an object that elicits attachment behavior), but they were otherwise isolated from other birds. These subjects displayed little aggression when they were subsequently reunited with a conspecific, indicating that the aggression-precluding effects of social housing are not limited to the particular social stimulus with which the ducklings are housed. In Experiment 3, ducklings were again housed with an imprinting object, but this time the object was behind glass, thereby precluding tactile contact with it. Since these birds also exhibited little aggression when reunited with a conspecific, it is apparent that visual stimulation from an imprinting object is sufficient in itself to preclude subsequent aggression. These findings suggest that stimulation that elicits attachment behavior is the critical factor mediating isolation-induced aggression.
