Weight differences in emotional responsiveness to proprioceptive and pictorial stimuli.

In 2 studies, 70 overweight and 76 normal-weight undergraduates were administered the Sadness and Elation components of the Nowlis Mood Adjective Check List to investigate weight differences in emotional responsiveness to proprioceptive and pictorial stimuli. Contrary to past evidence that overweight Ss are more emotional than normals, the emotional state of normal-weight Ss fluctuated with manipulations of their facial expression, whereas that of overweight Ss did not respond to these proprioceptive cues. Although research employing affectively loaded pictures found overweight Ss to be more emotionally responsive than normals to these external stimuli, no such weight differences were obtained when less polarized pictures were used in the present studies. It is concluded that even though overweight Ss were more emotionally responsive to extremely polarized external stimuli that demand perception, they were less responsive to proprioceptive stimuli derived from facial expressions and equally responsive to moderately polarized pictorial stimuli.

Externality as a function of obesity in children: Pervasive style or eating-specific attribute?

The developmental sources of the link between stylistic externality and food-related externality found in the obese by S. Schachter and his associates (e.g., Schachter and J. Rodin, 1974) were explored by testing whether the externality phenomena that have been found to differentiate obese and normal adults are also discriminators of obese and normal children. Based on teacher ratings of obesity, 28 distinctly overweight and 28 normal weight Ss in Grades 2–5 were selected. Ss were assessed on 3 measures (a) the eating of shelled or unshelled peanuts, (b) their estimations of the length of a boring or interesting film, and (c) their rod-and-frame test-measured field dependence. Results suggest that obese children as young as 7–22 yrs of age show an external responsiveness to salient food cues but do not yet show a generally external perceptual style.

Development of recognition of emotions: Children's reliance on situational and facial expressive cues.

Examined the influence of nondiscrepance and discrepance between situational and expressive cues on children's emotion recognition. Videotaped episodes in which actors portrayed emotions were presented to 96 4–8 yr old girls. When cues were nondiscrepant, Ss were better at all ages in recognizing happiness, fear, sadness, anger, and disgust than shame and contempt. This was interpreted as reflecting differences in complexity of emotions. When cues were discrepant, Ss preferred cues depicting the most recognizable emotion—that is, cues of simple emotions in preference to cues of complex emotions, and emotional cues in preference to neutral cues. Contrary to expectations, Ss did not rely on more salient cues in preference to less salient cues. Ss' responses to questions regarding the perceived cues reflected a developmental trend from noticing only 1 type of cue to considering both situational and expressive cues. This is interpreted as reflecting a development from centration to decentration. (27 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Some characteristics in affiliation motivation.

151 students in Officer Candidate School were given a measure of affiliation motivation. (1) Increased affiliation cues in the environment increase the level of both goal oriented and threat oriented responses. (2) Popularity is unrelated to level of affiliation motivation but does determine the extent to which the S is goal or threat oriented. (3) Those Ss with high internal affiliation motivation are more responsive to external affiliation cues than are Ss with low internal motivation. (4) Those Ss with high affiliation motivation tend to estimate their popularity level more accurately and to estimate it higher than Ss with low affiliation motivation.

Effect of external cues on the thinking behavior of obese and normal subjects.

Hypothesized that the thinking behavior of obese Ss is externally controlled to a greater extent than that of normals. 36 normal weight and 36 obese male undergraduates served as Ss. It was predicted that obese Ss would spend more time than normals thinking about an assigned topic of thought if there were topic-relevant external cues available, and less time than normals if there were no topic-relevant external cues available. With thinking measured directly by self-report and indirectly by distraction from pain, these predictions were confirmed. It is concluded that differences in eating behavior between obese and normal Ss can be explained by differences in thinking behavior. Therapeutic implications of the cognitive style of the obese are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Development of conversational responsiveness: Preschoolers' use of responsive listener cues and relevant comments.

Examined how the use of responsive listener cues (e.g., head nods, uh-hums, yesses, gazes, smiles) and relevant comments changes over the preschool years by videorecording 33 children (aged 29–67 mo) as they listened to an adult speaker talk about his experiences. Older Ss used more head nods and spent more time talking, smiling, and gazing than did younger Ss. In addition, age was significantly correlated with use of relevant comments but not the use of irrelevant comments. Furthermore, the Ss who used more responsive nonverbal cues tended to also engage in more responsive verbal behaviors. The relationship between the development of nonverbal and verbal behaviors is discussed. (40 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Age differences in using source-relevant cues.

Ss heard words originating from 2 speakers and later decided which of the 2 speakers said the words. Older adults had difficulty with source monitoring when perceptual cues from 2 sources were similar (2 female speakers), but this difficulty was overcome when perceptual cues were distinctive (a male and a female speaker) and were the only salient cues to source. Older adults also benefited from distinctive spatial cues when these were the only salient cues to source. Older adults, however, experienced difficulties in using multiple cues (both perceptual and spatial) to source effectively, whereas younger adults were able to use multiple cues to enhance their source-monitoring performance. It is suggested that age differences in source monitoring result from differential cue utilization. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Role of out-group cues in determining social identity.

Examined the role of out-group cues in determining social identity and guiding behavior in 2 experiments with 131 undergraduates. In Exp I, Ss were exposed to a cue either of an in-group (Ss' college), a relevant out-group (a rival college), or an irrelevant out-group (a baseball team). Ss examined a list of words and were later asked to recognize those they had seen from a larger list in which words related to the 3 groups were embedded. Results indicate that Ss made more false recognitions of in-group related words when a relevant out-group was salient than when an irrelevant out-group was salient. Exp II tested a behavioral implication of Exp I: Out-group salience increases adherence to an in-group norm. In the 1st phase of Exp II, Ss were divided into 2 groups and deliberated 2 civil suits. Ss' in-group favored the plaintiffs for both cases. Ss were divided into new groups for the 2nd phase, and the same procedure was followed. This time, however, the in-group favored the defendants. In the 3rd phase, Ss were exposed to a cue either of the out-group in Phase 1 or Phase 2. Ss' judgments for 2 new cases were biased in the direction of the norm of the in-group that was associated with the salient out-group. Ss favored the plaintiff (or defendant) when the 1st (or 2nd) out-group was salient. (14 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Contextual cues and release from proactive inhibition in young and old people.

Three experiments examined whether elderly people perform similarly to Korsakoff amnesics on tests of release from proactive inhibition (PI). In Exp I, with 20 18–36 yr old undergraduates, 20 64–77 yr old university alumni, 20 employed 21–43 yr olds, and 21 institutionalized but healthy 71–92 yr olds, only the latter Ss failed to release from PI, like Korsakoff amnesics, whereas all the other groups of Ss showed the normal release from PI. Exp II, with 12 institutionalized 64–90 yr olds and 12 25–47 yr old controls, showed that release from PI could be induced in institutionalized elderly, as in Korsakoff amnesics, by salient environmental cues that coincided with the category shift. Exp III, with 13 67–89 yr old institutionalized Ss and 12 22–42 yr old controls, demonstrated that even in the absence of a category shift, salient environmental cues could lead to smaller, but noticeable, release from PI in institutionalized elderly, but not in young controls. The similarity in performance between the institutionalized elderly and Korsakoff amnesics suggested that it results from a common neurological deficit.

Two studies on the language behavior of schizophrenics.

Tested L. J. Chapman's hypothesis that contextual constraints are less salient, and stronger meaning constraints more salient for schizophrenics than for normals, as was the hypothesis drawn from the works of K. Salzinger and of R. L. Cromwell and P. R. Dokecki that schizophrenics are overly constrained by immediate cues relative to distant ones. Ss were 3 groups of males at a VA hospital: 25 normal controls, staff members; 22 hospitalized controls, nonschizophrenic patients; and 71 schizophrenics. The Chapman hypothesis was supported only for disorganized schizophrenics and only when the ambiguous element being considered was lexical. The immediacy hypothesis was supported with regard to semantic constraints. (25 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Story comprehension and recall in learning-disabled versus normal college students.

24 learning-disabled (LD) and 24 normal college students rated stories on the importance of their idea units. LD Ss showed significantly less agreement on their importance ratings than the normal Ss. Ss also selected 12 idea units as retrieval cues, one group before and the other after recall. This task showed that normal Ss selecting cues after recall used a different strategy than those selecting cues before recall; LD Ss did not vary their cue-selection strategy as a function of experience. In spite of these differences, recall increased significantly at higher importance levels for both ability groups, and recall did not differ for LD and normal Ss who selected retrieval cues after recall. Cue selection before recall, however, depressed performance of LD Ss relative to that of the normal Ss. (14 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of degree of obesity, age of onset, and weight loss on responsiveness to sensory and external stimuli.

Four experiments tested responsiveness to external and sensory stimuli in human females who differed in degree of overweight and in age of onset of their obesity. A total of 196 overweight Ss, ranging in age from 12–58 yrs and representing both juvenile- and adult-onset obese groups, served as Ss; in Exps I and IV, a total of 14 normal-weight Ss were used as controls. The effects of weight loss on external responsiveness were assessed by testing Ss before and after weight reduction in order to determine the role of energy deficit and deprivation in mediating heightened responsiveness to external cues. There was no significant positive correlation between degree of overweight and degree of external responsiveness. In general, the age of onset of obesity was also not a factor in the degree of externality. Weight loss did not change responses to visual and cognitive cue salience manipulatons in measures of feeding, emotionality, time perception, and short-term recall, while responsiveness to variations in taste palatability increased following weight reduction. While external cue responsiveness does not appear to result from adiposity per se or from deprivation, responsiveness to taste stimuli may reflect these parameters. The role of external and sensory cues in the development and maintenance of obesity is discussed. (42 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Impulsive motor behavior: Effects of personality and goal salience.

This experiment used a circle tracing paradigm to extend our recent theoretical development concerning the contributions of extraversion and neuroticism to impulsive performance on continuous motor tasks. Ss (N?=?137) completed the Eysenck Personality Questionnaire and were randomly assigned to 1 of 2 circle conditions: The goal condition provided subjects with a salient behavioral end point for their tracings, whereas the no-goal condition promoted behavioral uncertainty. In both conditions, Ss were asked to trace the circle under neutral and inhibition instructions. Using J. A. Gray's impulsivity and anxiety dimensions to group subjects, impulsive subjects under inhibition instructions displayed significantly faster tracing speed than nonimpulsive subjects in the presence of a salient goal, whereas anxious subjects appeared behaviorally impulsive in a situation promoting uncertainty and response conflict. Conceptualizing impulsivity and anxiety in terms of extraversion and neuroticism, with impulsive Ss as neurotic extraverts and anxious Ss as neurotic-introverts, it is proposed that Ss' level of extraversion determines the type of stimuli to which they are responsive and that level of neuroticism influences the magnitude of this reaction.

Interaction of fear and guilt in inhibiting unacceptable behavior.

80 male college students completed the Mosher Incomplete Sentences Test which was scored for sex guilt. The Ss were assigned by alternation to a fear-reduction or fear-induction experimental condition which preceded a perceptual defense task. The results supported the prediction derived from social learning theory that the inhibitory behavior of Ss who score low on a measure of sex guilt is more influenced by situational cues relevant to the probability of external punishment for sex-related behavior than is the inhibitory behavior of the high-sex-guilt group. The results suggested that the high-sex-guilt S is relatively insensitive to situational cues concerning the probability of external punishment.

Ontogeny of thermal and olfactory determinants of huddling in the rat.

In Exp I, in standardized tests of huddling behavior, 64 5-, 10-, 15-, and 20-day-old Sprague-Dawley rat pups spent substantial and equivalent amounts of time with an immobile rat or a heated, fur-covered tube, which suggests that the conspecific and inanimate stimuli were equally attractive to the pups. In Exp II, with 32 Ss, 2-choice preference tests showed developmental differences in attraction. Younger Ss preferred to huddle with the warmer, inanimate target, whereas older Ss preferred the conspecific. The emergent conspecific preference appears mediated by attraction to species odors. In Exp III (64 Ss), the 5- and 10-day-olds huddled equally with an immobile rat and an immobile gerbil (stimuli with similar thermal and tactile properties), but older Ss preferred the conspecific. In Exp IV, with 16 15-day-old and 16 20-day-old Ss, intranasal zinc sulfate treatment eliminated preference for the conspecific but did not disrupt huddling per se. Results from all experiments show that thermal cues were sufficient to elicit huddling at all ages, but olfactory cues became a more salient influence before weaning. An ontogenetic transition from "physiological" to "filial" huddling is discussed in terms of changes in sensory control of early behavior.

A test of heightened external responsiveness in an alcoholic population.

In an effort to extend S. Schachter's stimulus-bound hypothesis from obesity to alcoholism, comparisons among 45 alcoholic, obese, and nonalcoholic normal-weight outpatients at a VA hospital were made on 4 measures of externality. It was predicted that alcoholics and obese persons would be significantly more responsive to external stimuli than control Ss, and alcoholics and obese persons would not differ significantly from each other. The predictions were confirmed on 2 measures, 1 of which (a reaction time task) was a replication from Schachter and J. Rodin (1974). The methodological adequacy of the other 2 tests is questioned, especially with respect to their validity in measuring externality. Results lend some support to the hypothesis that alcoholics, like the obese, exhibit a differential reliance on external and internal cues. The implications of heightened external responsiveness for understanding craving and loss of control, 2 defining symptoms of alcoholism, and recent treatment strategies are discussed.

Blood alcohol level discrimination by alcoholics: The role of internal and external cues.

Two groups of 4 chronic alcoholics lived in Rutgers' Alcohol Behavior Research Laboratory for separate 2-wk periods. During that time, Ss were taught to attend either to internal or to external cues to blood alcohol level (BAL). Mean age of the internal group was 36.2 yrs, and that of the external was 35.7 yrs. Internal Ss completed the Body Sensation Checklist and the Mood Adjective Check List. During a single training session, Ss received feedback on actual BAL following each of their BAL estimates. During pretraining and posttraining sessions, assessments of BAL estimation accuracy were obtained in the absence of feedback. Prior to training, both groups were equally inaccurate in estimating BAL. During training, when accurate BAL feedback was provided, estimation accuracy increased significantly for both groups. Once feedback of actual BAL was removed during the posttraining test session, however, only externally trained Ss maintained the ability to estimate BAL accurately. It is concluded that unlike the nonalcoholic Ss studied by H. Huber, R. Karlin, and A. E. Nathan (1976), the alcoholic Ss of the present study did not learn to discriminate BAL on the basis of internal feelings and sensations nearly as adequately as they did when they referred to external cues. It is suggested that these findings may have important implications for the clinical application of BAL discrimination training.

Generation effects in free recall: Further support for a three-factor theory.

A framework is presented that helps explain and predict generation effects in free recall (for between-Ss manipulations of generating vs reading). When the targets share common features and when that shared information is salient to Ss, Ss will exploit that information to help generate the target items. This produces more relational processing among the targets (relative to reading), enhancing free recall. Consistent with this idea, when shared information (among targets) was salient, generation effects in free recall were found under encoding conditions that can disrupt generation effects in cued recall (e.g., pairing targets with unrelated cues). Further, within the same list, generation effects emerged in free recall for targets that were processed after shared information became evident but not for targets processed prior to the availability of the shared information. In recognition, generation effects were found for targets regardless of when they were processed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dissociation of spatial discrimination deficits following frontal and parietal lesions in monkeys.

Gave 40 rhesus monkeys dorsolateral prefrontal, posterior parietal, or inferotemporal lesions. 4 additional Ss served as unoperated controls. Ss then received 2 forms of spatial discrimination training, based on body position ("egocentric" cues) and on the position of an external referent ("allocentric" cues), respectively. On the former, a place discrimination reversal, frontal Ss were impaired but not parietals. On the latter, a landmark discrimination reversal, parietal Ss were impaired but not frontals; this result was also obtained on a test involving distance discrimination without reversal. Finally, the inferotemporals but not the frontals or parietals were impaired on a nonspatial object discrimination reversal. Results suggest that the 2 modes of spatial orientation, egocentric and allocentric, are related to frontal and parietal mechanisms, respectively. (18 ref.)
