Coordination of the upper and lower extremities

Simultaneous walking and hand clapping were utilized to examine the patterns of coordination between upper and lower limbs. Eighteen normal adult subjects were filmed at high speed under instructions to: (a) walk and clap at a self-determined “preferred” speed, (b) walk as fast as possible while clapping at the preferred speed, (c) walk at the preferred speed while clapping as fast as possible and (d) walk and clap as fast as possible. Temporal data and individual patterns of phase relations were analyzed. Results indicated a disruption of the preferred clap cycle when combine with fast walking. The degree of disruption was a function of the individual coordinative pattern at the preferred rate. It is concluded that: (a) the temporal patterning of the clap cycle can be dictated by the step cycle, (b) heel strike is the point about which the clap cycle is modulated, and (c) subjects can select from various modes of phase linkage.     

INDUCTION AND MAINTENANCE OF SWALLOWING RESPONSES IN INFANTS WITH DYSPHAGIA

A treatment package was used to induce and maintain swallowing with three infants who did not swallow food or liquid. Prior to treatment, they received all nutrition and hydration via gastrostomy tube feedings. The treatment package consisted of least-to-most intrusive physical prompts, an eliciting stimulus, contingent social reinforcement, and repeated trials to induce and maintain swallowing. The design combined elements of reversal and changing criterion designs for all three infants. The package was applied across feeding devices (nipple, cup, spoon), situations (liquid, pureed foods), and persons (trainer, primary nurses, mothers). The number of swallows or ounces per feeding (from 0 to 8 ounces) and the number of feeding sessions per day (from one to five) were progressively increased. In each case, the infant received baseline conditions alternated with the treatment package. Follow-up probes were done at 15 months, 21 months, or 24 months, respectively, after the last phase for the three patients. The package was successful in that the gastrostomy tube was no longer needed for Patients 1 and 3. Patient 2 maintained functional swallowing responses but received supplemental gastrostomy feedings because of unrelated medical problems. Results are discussed in terms of the need to isolate components of the package. The package can be used in cases in which the preexisting treatments (reinforcement with preferred foods, force-feeding) are not feasible because of age, physical fragility, or the lack of a swallowing response following the presentation of food.     

The effects of information exchange and communication in an asymmetrical negotiation situation

Seventy-eight dyads of male university students participated in a bargaining experiment. The bargaining situation was asymmetrical insofar as the two players had different payoff possibilities. Experimental instructions did not provide information about the opponent's payoff possibilities but players could ask each other for such information (except in the control condition). It was found that the players in the advantaged position (with better payoff possibilities) bluffed more frequently and communicated less with the opponent than their disadvantaged opponents. But there were no differences in the frequency of refusing to give requested information, nor in the frequency of requesting information. Verbal communication opportunities reduced the frequency of bluffing (false information) but did not by themselves lead to smaller payoff differences between the two players. Payoff differences were smallest when information exchange was obligatory and truthful and they were greatest when neither information exchange nor communication was possible.     

Collective self-esteem consequences of outgroup derogation when a valued social identity is on trial

A structural equation model tested the role of degree of identification with a group (Americans) and level of collective self-esteem as determinants of outgroup derogation under identity-threatening and non-threatening conditions. High identification and reductions in collective self-esteem following a threat to that identity lead to outgroup derogation, but level of collective self-esteem did not predict outgroup derogation in the no-threat condition. The consequences of derogating both threat-relevant (Russians) and threat-irrelevant nationalities for subsequent self-esteem were assessed. As predicted by social identity theory, higher amounts of derogation of the threat-relevant outgroup in the identity-threatened condition elevated subsequent collective self-esteem. Derogation of threat-irrelevant outgroups did not have this positive esteem consequence; in fact, increased derogation of irrelevant outgroups reduced subsequent self-esteem. In the no-threat condition, amount of derogation directed towards either type of outgroup did not significantly influence subsequent self-esteem, with the overall pattern being opposite to what was observed in the threat condition. Implications for theories concerning self-processes as instigators of outgroup derogation and the consequences of intergroup comparisons for collective self-esteem are discussed.     

Racism,Counterfactual Thinking,and Judgment Severity1

Two contrasting models of the effects of motivational influences on the relationship between counterfactual thinking and social judgment were tested, using a modified version of Wells and Gavanski's (1989) cab driver vignette. Undergraduates (N= 208) assigned blame to a negligent white or black target after imagining how the target's alternative behavior could have either easily or improbably averted two accident-related fatalities. Results suggested that motivational variables such as racism moderate the relationship between counterfactual thinking and judgment severity rather than directly affect the counterfactual thinking process itself. Implications for current conceptions of both counterfactual thinking and racism are discussed.     

Distorted distance estimation induced by a self-relevant national boundary

Six experiments explored the possibility that the categorization of self versus not-self can distort visual estimations of distance. In Experiments 1-3, Americans overestimated the distance between a U.S. location and a foreign location relative to a visually equidistant U.S. location. In Experiment 4, Canadians overestimated foreign relative to Canadian locations. Experiment 5 showed that this effect occurs even when the domestic context is not physically contiguous. Experiment 6 showed that distance distortion occurs only when crossing one’s own border to a foreign location, not when crossing borders from one foreign location to another. Thus, crossing the psychological boundary between self and not-self creates a visual illusion that distorts on-line distance estimates.     

Context matters: Explicit and implicit reminders of ingroup privilege increase collective guilt among foreigners in a developing country

We test three ways context matters in the study of intergroup inequality: where participants are approached, who interacts with participants, and how researchers ask participants questions. Regarding how, we replicate a finding that framing intergroup inequality as outgroup disadvantage rather than ingroup privilege reduces collective guilt in a novel context. Regarding where, we go beyond the laboratory to test foreigners in Nepal—a country where inequality is highly salient. Regarding who, we had participants approached by an ingroup (foreign) experimenter or an outgroup (Nepalese) experimenter. We found an outgroup disadvantage framing reduced collective guilt relative to ingroup privilege framing, but only when delivered by an ingroup member. This highlights the importance of taking where, who, and how into account to fully understand the contextual nature of intergroup emotion.     

Group identity as a source of threat and means of compensation: Establishing personal control through group identification and ideology

Compensatory control theory proposes that individuals can assuage threatened personal control by endorsing external systems or agents that provide a sense that the world is meaningfully ordered. Recent research drawing on this perspective finds that one means by which individuals can compensate for a loss of control is adherence to ideological beliefs about the social world. This prior work, however, has largely neglected the role of social groups in defining either the nature of control threat or the means by which individuals compensate for these threats. In four experiments (N = 466), we test the possibility that group‐based threats to personal control can be effectively managed by defensively identifying with the threatened group and its values. We provide evidence for the specificity of these effects by demonstrating that defensive identification and ideology endorsement are specific to the content of the group‐based threat.     

Remembering historical victimization: collective guilt for current ingroup transgressions

The authors examined the consequences of remembering historical victimization for emotional reactions to a current adversary. In Experiment 1, Jewish Canadians who were reminded of the Holocaust accepted less collective guilt for their group's harmful actions toward the Palestinians than those not reminded of their ingroup's past victimization. The extent to which the conflict was perceived to be due to Palestinian terrorism mediated this effect. Experiment 2 illustrated that reminding Jewish people, but not non-Jewish people, of the Holocaust decreased collective guilt for current harm doing compared with when the reminder concerned genocide committed against another group (i.e., Cambodians). In Experiments 3 and 4, Americans experienced less collective guilt for their group's harm doing in Iraq following reminders of either the attacks on September 11th, 2001 or the 1941 Japanese attack on Pearl Harbor compared with a historical victimization reminder that was irrelevant to the ingroup. The authors discuss why remembering the ingroup's past affects responses to outgroups in the present.
