SEX DIFFERENCES IN CONFORMITY: STATUS AND GENDER ROLE INTERPRETATIONS

The experiment examines status and gender role explanations of the tendency for women to conform more than men in group pressure settings. Subjects believed they were assigned to groups containing two males and two females in addition to themselves and received these other group members' opinions, which were represented as deviating from the opinions that subjects had given earlier. Subjects then gave their opinions with the other group members either having or not having surveillance over these opinions. In addition, subjects were required to form impressions of each other's likability or expertise. The findings indicate that subjects' sex and age affected the extent of their conformity. Among older (19 years and older) subjects, females conformed more with surveillance than without it, whereas surveillance did not affect males' conformity. Among younger (under 19 years) subjects, surveillance had no effects. Analysis of sex differences revealed that older females were significantly more conforming than older males when under surveillance as well as when subjects formed impressions of one another's likability. Among younger subjects, there were no sex differences. These findings are discussed in terms of the theories that (a) both sex and age function as status characteristics and (b) gender roles determine conformity.     

Parental stress, coping styles, and social supports in chinese families with hepatitis-b-carrying children

The purpose of the study was to examine the hypothesis that parents’ psychological well-being can be affected by a child’s illness and their social situations. In this study, we discuss the roles of coping, social support and situational context related to stress. These factors cannot only affect stress levels but can also influence whether the individual adopts a certain type of coping style for stressful events. Parental stress, coping styles and social support were compared between groups of parents of Hepatitis B virus (HBV) carrier children or healthy children. Results showed that parents of affected children were significantly more stressed and psychologically at risk, and tended to mobilize personal resources and to rely more on themselves to solve stressful life events. They also sought help from social resources more often than did parents of healthy children. Parents of healthy children had a higher number of close friends and relatives available to them. Ninety Chinese parents and their HBV or healthy children participated in this study. These families were all living in the city of Guangzhou, China.     

Pattern-directed attention in uncertain-frequency detection

The role of early pattern components as cues in uncertain frequency detection was investigated in four probe-signal experiments. Listeners heard two consecutive presentations of one of two 12-tone patterns in a noise background. One presentation of the pattern was complete, whereas the other was missing the 11th (primary) tone. Listeners were required to indicate which presentation was complete. On 20% of the test trials, the 11th component of the complete pattern was replaced with one of four probe tones. The results indicated that listeners were more sensitive to the primary tone than to probe tones, and this selective sensitivity changed on a trial-by-trial basis as a function of the attentional cues provided by early pattern components. The data suggested two cue functions: (1) an “informational” function in providing information regarding which of two primary tones is likely to occur on a given trial, and (2) a “frequency” function that “automatically” directs listening to an appropriate frequency range and narrows or “fine tunes,” the listening band.     

Negotiation versus influence

The bargaining and minority influence literatures offer contradictory theories for the efficacy of compromise for influence. Assuming that the relative merits of these two classes of theories lie in their concentration on the public versus the private aspect of influence, we predicted that consistency (without compromise) would be more effective for attitude change but that compromise would be more effective for public concessions. We further predicted that the timing or context of the compromise could change the meaning and the consequences of that strategy. In particular, compromise ‘at the last minute’ was assumed to be a negotiating tactic that fostered both public concessions and private attitude change. The predictions were generally confirmed.     

Detecting phonemes and letters in text: Interactions between different types and levels of processes

In six experiments, subjects detected phonemes or letters in text presented auditorily or visually. Experiments 1 and 2 provided support for the hypothesis that a mismatch between the phoneme and letter representations of a target leads to detection errors. In addition, visual word unitization processes were implicated. Experiments 3 and 4 provided support for the hypothesis that the Gestalt goodness of pattern affected detection errors when subjects searched for letters. Experiments 5 and 6 demonstrated that the effects of unitization on the detection of letters in common words were decreased by altering the familiar configuration of the test words. The combined results of all six experiments lead to the conclusion that both visual and phonetic processes influence letter detection, that these processes communicate through a type of cross-checking, and that there are at least two levels of visual (and perhaps of phonetic) processing involved in the letter detection task.     

The influence of the Y-chromosome of Rb/1Bg mice on agonistic behaviors

Males of the Rb/lBg and C57BL/10Bg strains, as well as of the Bl0RblF, and RblBlOF1, reciprocal hybrids, were tested for aggression over three daily trials beginning at 50 days of age. The BlORblF, hybrids were sired by Rb/lBg males, and the RblBlOF, hybrids were sired by C57BL/10Bg males. The mean scores for the agonistic acts of chase, wrestle, flank-bite (but not tail rattle or attack), and the mean “aggression” score (but not mean latencies to first agonistic act or first attack) were significantly higher for BlORblF, than for RblBlOF, hybrids. These findings are consistent with the hypothesis that some aspect(s) of the Rb/lBg Y-chromosome strain can influence the occurrence of some of the motor patterns of offense but not defense. The Y-chromosomes of the DBA/1, DBA/2, CBA, and PHH inbred strains have a similar effect on agonistic behaviors.
