Bilateral lesions of the insular cortex or of the prefrontal cortex block the association between taste and odor in the rat

The neural basis for the association between taste and odor was investigated in the rat. First, behavioral procedures to study the mechanisms underlying the association between qualitative aspects of the odor and taste in rats were developed. Rats were presented with several pairings of the 0.3 mol/L NaCl solution and a flavor, and pairings of distilled water and another flavor. Then the rats received an IP injection of a furosemide to develop sodium deficiency. On the next day, the rats were presented with either of two types of odor-flavored water: water in which the flavor had been paired with NaCl, or water in which the flavor (grape or coffee) had been paired with distilled water. Normal rats avoided ingesting the water flavored with the odor previously paired with NaCl. Sodium-deprived rats, however, ingested the water flavored with that odor. Rats with lesions in either the insular cortex or in the prefrontal cortex neither preferred nor avoided the water flavored with the odor paired with NaCl. It was concluded that rats acquire association between taste and odor, and that the insular and the prefrontal cortices of the rats were involved in this association.     

高低自我监控者在不同互动情境中的被洞悉错觉

用Snyder的自我监控量表,从大学生中筛选出典型高低自我监控者。要求他们不动声色地喝下1杯醋和4杯水,而后,让观众根据他们的表现去辨别饮料的味道,并让被试预测可能猜中的人数。在实验1中,被试和观众以录像为媒介间接的互相推测;在实验2中,被试和观众现场直接的互相推测。两个实验都包括高低自我监控者各21名。实验结果表明,自我监控水平对被洞悉错觉有明显的影响,在直接和间接两种互动情境中,低自我监控者的被洞悉错觉都比高自我监控者强烈。互动情境对高自我监控者有明显的影响,在间接的互动中,高自我监控者出现了明显的被洞悉错觉;而在直接的互动情境中,低自我监控者的被洞悉错觉依然非常明显,高自我监控者则趋于消失     

Reliability and standardization in the assessment of self-reported headache pain

The efficacy of a treatment intervention for head pain is typically evaluated by self-reported data. Self-monitoring schedules used to collect these data vary extensively across studies. The present article reviews conceptual and methodological problems with these self-report inventories. In addition, the most promising procedure was implemented in a study designed to measure the reliability of self-reported headache pain levels. One-hundred twenty-four college students self-monitored headache pain over an 8-week period. Three objective procedures were used to detect inaccurate recording. Subjects were also asked, in a post-experimental questionnaire, to subjectively rate the degree to which they complied with the experimenters' instructions regarding the self-monitoring procedures. Forty percent of the subjects were found to be noncompliant based on the detection techniques. However, responses to the postexperimental questionnaire indicated this to be a conservative estimation of noncompliance. There was no consistent difference between the postexperimental questionnaire for the subjects detected and those not detected. Results are discussed with relation to the need for researchers to adopt a standard methodology for (1) measuring self-reported headache pain and (2) reporting reliability data.Portions of these data were presented at the meeting of the Association for Advancement of Behavior Therapy, Chicago, November 1978.     

A Comparison of Video Feedback and In Vivo Self-Monitoring on the Social Interactions of an Adolescent with Asperger Syndrome

Difficulties with social interactions and restrictive and repetitive interest patterns or behaviors are common among individuals with Asperger syndrome. These difficulties often pose barriers to establishing and maintaining social relationships. In the current study, 2 different interventions were compared that focused on improving the social interactions of a 14-year-old adolescent with Asperger syndrome. A reversal design was used to compare the effectiveness of video feedback and in vivo self-monitoring on inappropriate and appropriate social interactions during activities with a teacher. The procedures were replicated during activities with peers, and generalization was assessed during activities with the adolescent’s mother. Although video feedback resulted in slight reductions in inappropriate behavior, larger reductions occurred during in vivo self-monitoring. Treatment acceptability data indicated high participant satisfaction with both interventions; however, the in vivo self-monitoring was rated as slightly preferred.     

Electrical aversion therapy with alcoholics: An analogue study

Chronic alcoholic patients matched on age, education and length of problem drinking were assigned to one of three treatment conditions, with 10 subjects in each group: (1) Electrical Aversion Conditioning (high shock paired with alcohol sips); (2) Control Conditioning (very low shock paired with alcohol sips); and (3) Group Therapy (confrontation psychotherapy). Groups 2 and 3 were included to control for possible ‘attention-placebo’ and expectancy factors involved in the conditioning procedures. Subjects in each group were given instructions designed to produce high expectancy for therapeutic success. Pre-post measures of alcohol consumption and attitudes toward alcohol were obtained using an analogue ‘taste test’ assessment procedure. No statistically significant differences in reduced alcohol consumption or attitudes toward alcohol were found among the groups. Trends in the data support the contention that effects of electrical aversion may be more related to such factors as therapeutic instructions, expectancy, specificity of the procedure or experimental demand characteristics than to conditioning factors.     

NICOTINE FADING AND SELF-MONITORING FOR CIGARETTE ABSTINENCE OR CONTROLLED SMOKING

This study compared four treatment approaches to cigarette smoking: (1) a nicotine fading procedure, in which subjects changed their cigarette brands each week to ones containing progressively less nicotine and tar; (2) a self-monitoring procedure in which subjects plotted their daily intake of nicotine and tar; (3) a combined nicotine fading/self-monitoring procedure; and (4) a slightly modified American Cancer Society Stop Smoking Program. Thirty-eight habitual smokers were assigned to one of the treatment groups. The study had two goals: (1) to achieve a clinically significant percentage of abstinence, and (2) to reduce the nonabstainers' smoking to a “safer” level by having them smoke low tar and nicotine cigarettes. The 18-month followup results showed that the nicotine fading/self-monitoring group was the most successful: 40 per cent were abstinent and all who had not quit were smoking cigarettes lower in tar and nicotine than their baseline brands. Half the nonabstainers had decreased their rate of smoking relative to baseline while the other half had increased. Furthermore, the fading/self-monitoring group achieved the largest reductions from baseline in daily nicotine and tar intake (61% and 70% respectively). The results suggest that the study's goals were achieved and that the nonaversive combined procedure could be used to treat not only habitual smokers but also smokers with severe cardiovascular and respiratory problems, because it does not have some of the inherent limitations of the successful aversive smoking cessation procedures.     

Restraint and internal responsiveness: effects of placebo manipulations of hunger state on eating

Restrained and unrestrained subjects were given a "vitamin" (placebo) prior to an ad-lib taste test. Subjects were either told nothing about the placebo or told that previous subjects had reported that the vitamin had made them feel either hungry or full. As predicted, restrained subjects, in two separate studies, behaved in accordance with placebo messages, eating more when given "hungry" messages than when given "full" messages. Unrestrained subjects showed an apparent reverse-placebo effect; they ate less ice cream when given "hungry" information than when given "full" information. Hunger ratings did not parallel eating behavior; possible explanations for this discrepancy are considered. We conclude that unresponsiveness to internal hunger state, and an overreliance on external cognitive cues, characterizes restrained but not unrestrained individuals.     

Self-Monitoring and Idiographic Measures of Behavioral Variability Across Interpersonal Relationships

ABSTRACT Sixty-five subjects were assessed by a computer program that asked them to list the primary people they interact with, the situations they inhabit with these people, and the traits and behaviors they typically show with these people The program stored these data as a tree of information Subjects also kept detailed behavioral diaries over a 10-day period and completed Snyder's (1974) Self-Monitoring Scale The consistency of subjects' behaviors and settings over interpersonal relationships was computed from the computer data and from behavioral diaries Results indicated that consistency as assessed idiographically from computer data, consistency as assessed idiographically from diaries, and self-monitoring were intercorrelated These results illustrate the possibility of wedding idiographic and nomothetic approaches in research on the consistency and variability of behavior     

A comparison of the relative efficacy of self-control therapy and a behavioral problem-solving therapy for depression in children

Twenty-nine children 9 to 12 years old who were identified as moderately to severely depressed using the Children's Depression Inventory were randomly assigned to either a self-control, behavioral problem-solving, or waiting list condition. The self-control treatment focused on teaching children self-management skills. The behavioral problem-solving therapy consisted of education, self-monitoring of pleasant events, and group problem solving directed toward improving social behavior. Subjects were assessed pre-and posttreatment and at 8-week follow-up with multiple assessment procedures and from multiple perspectives. At posttreatment, subjects in both active treatments reported significant improvement on self-report and interview measures of depression while subjects in the waiting list condition reported minimal change. Results were maintained at follow-up. The general success of the experimental treatments was discussed and recommendations for further treatment components were provided.Second authorship on this article is shared by Drs. Reynolds and Kaslow. The authors would like to thank Mr. Ed Guzwieski, Principal, and the teachers of Oregon Middle School for their cooperation with this study.

Experimentally induced taste aversions in humans: effects of overshadowing on acquisition.

This study used vection-induced symptoms of motion sickness as an unconditioned stimulus to condition food aversions in humans and to evaluate the efficacy of an overshadowing agent (novel flavored candy: CS2) to attenuate acquisition of the aversion. Subjects unfamiliar with a target food (CS1) were assigned to one of the following three groups which were identical except for order of exposure to stimuli: Taste Aversion Group (CS1-US-CS2-Test), Control Group (US-CS1-CS2-Test), and Overshadowing Group (CS1-CS2-US-Test). Subjects were tested on aversion ratings and consumption of the target flavor and ratings of the overshadowing agent. Subjects in the Taste Aversion group rated the target flavor as significantly more aversive and consumed less of it, although not significantly so, that did those in the Control group. The Overshadowing group consumed significantly more of the target food than did the Taste Aversion Group. Considering only subjects unfamiliar with the overshadowing agent, those in the Overshadowing group rated the agent (CS2) as significantly more aversive than the Taste Aversion and Control groups. Implications of these findings to taste aversions in humans are discussed.     

SELF-MONITORING OF ATTENTIONAL BEHAVIOR VERSUS SELF-MONITORING OF PRODUCTIVITY: EFFECTS ON ON-TASK BEHAVIOR AND ACADEMIC RESPONSE RATE AMONG LEARNING DISABLED CHILDREN

I investigated the differential effects of self-monitoring of attentional behavior and self-monitoring of productivity on on-task behavior and academic response rate. Subjects were four learning disabled children with significant attentional problems. Results indicated relatively equivalent increases in on-task behavior over baseline during all treatment phases. Academic response rate also improved under both interventions, with self-monitoring of productivity showing a superior effect for one subject, an equivalent effect for one subject, and less dear results for two subjects.     

COMPETITION BETWEEN POSITIVE AND NEGATIVE REINFORCEMENT IN THE TREATMENT OF ESCAPE BEHAVIOR

We compared the effects of reinforcing compliance with either positive reinforcement (edible items) or negative reinforcement (a break) on 5 participants' escape-maintained problem behavior. Both procedures were assessed with or without extinction. Results showed that compliance was higher and problem behavior was lower for all participants when compliance produced an edible item rather than a break. Treatment gains were achieved without the use of extinction. Results are discussed regarding the use of positive reinforcement to treat escape behavior.     

Expressive control,expressive consistency,and the correspondence between expressive behavior and personality1

Does expressive behavior reflect personality? This paper proposes that expressive control is an important “moderating variable” affecting expressive behavior, expressive consistency, and the correspondence between expressive behavior and personality. To demonstrate this, a study was carried out in which 68 subjects were selected, according to a 2×2×2 factorial design, who were low and high on assessed extraversion, neuroticism, and self-monitoring (a measure of expressive control). Subjects were then videotaped as they role-played being teachers. A number of specific expressive behaviors were measured (subjects' stride length, graphic expansiveness, percent of forward eye-contact, and percent of time talking), and also groups of naive judges rated how “extraverted” and “anxious” subjects appeared. The following results supported our hypothesis: (1) Self-monitoring was significantly related to subjects' expressive behaviors and judged personalities, while assessed extraversion and anxiety were not. (2) Expressive control was used to suppress the “accurate” display of anxiety but not extraversion. (3) Bodily expression was less controlled than facial or vocal expression. And (4), persons low and high on self-monitoring showed different patterns of cross-situational and cross-channel (face, body, voice) expressive consistency.     

Psychophysics of taste lateralization on anterior tongue

There have been very few investigations of the spatial properties of taste stimuli localized to specific areas of the oral cavity. This is surprising, since the spatial localization of taste sensations may contribute to the overall taste percept, much as do quality, intensity, and the temporal characteristics of tastes. The difficulty in eliminating the confounding factor of a tactile sensation may partially account for the paucity of such studies, since a gustatory stimulus cannot be presented as a liquid without a tactile component. As a step toward understanding the localizability of gustatory sensations, we designed a yoked stimulator and an experimental procedure to control for tactile cues. Lateral discrimination was evaluated at the tip of the tongue with four taste stimuli (sodium saccharin, sodium chloride, citric acid, and quinine hydrochloride) by presenting a taste and a blank solution simultaneously at two locations on the tongue. We found that subjects could lateralize all four taste stimuli in the absence of any discriminative tactile cues. Subjects' ability to lateralize varied as a psychometric function of the stimulus concentration. Detection thresholds, measured in a forced-choice two-interval staircase procedure with the same yoked stimulator that was used in the lateralization task, were always lower than lateralization thresholds, and both lateralization and detection thresholds were correlated within subjects. Subjects were unable to lateralize taste cues on a nongustatory surface under the upper lip at the highest tested concentrations, at which performance was 100% on a gustatory surface (dorsal anterior tongue). These results show that (1) taste compounds can be lateralized in the absence of any discriminative mechanical cue (but only on the gustatory epithelium) and (2) although the localization of a compound does not logically require conscious detection of the taste (cf. blind sight), subjects always detected a taste when they were able to lateralize.     

Nicotine fading,self-monitoring and cigarette fading to produce cigarette abstinence or controlled smoking

This study developed and evaluated a smoking-treatment program. Twelve subjects were randomly assigned to one of two groups within a multiple baseline design. Subjects were first given a nicotine-fading and self-monitoring procedure for 3 weeks in which they changed their cigarette brands each week to ones containing progressively less nicotine and tar and plotted their daily intake of the two substances. Those subjects unable to quit smoking were then given a cigarette-fading procedure in which they systematically reduced the number of cigarettes smoked for 3 weeks. The study had two goals: (1) to achieve a reasonable percentage of abstinence; and (2) to reduce non-abstainers' smoking to a ‘safer’ level by having them smoke very low tar and nicotine cigarettes. The 12-month follow-up results revealed that 33% of the subjects were abstinent and all non-abstainers were smoking cigarettes lower in tar and nicotine than their baseline brands. Half the non-abstainers had decreased their smoking rate relative to baseline while the other half had increased. The subjects decreased their daily nicotine intake by 13.3 mg (81.6% reduction from baseline) and tar intake by 218.2 mg (85.5% reduction from baseline). These results suggest that the study's goals were achieved and that the non-aversive combined procedure could be used to treat not only habitual smokers but also those with cardiovascular and respiratory problems who cannot be treated by smoking-cessation procedures that use cigarette smoke as the aversive stimulus. Finally, a least-restrictive model for treating smoking is proposed and discussed.     

The effectiveness of visual and gustatory conditioned stimuli in human classical aversive conditioning with electric shock

Thirty-six undergraduate volunteers, divided into three equal groups, were given electric shock while sipping a colored, unflavored solution (Group I): a flavored, colorless solution (Group 2); or a colored, flavored solution (Group 3), in order to determine whether human Ss respond differentially to visual and gustatory cues when the UCS is aversive electric shock. Using a standard classical discrimination procedure, the CS + was blue water for Group 1, citric acid solution for Group 2, and blue citric acid solution for Group 3. For all groups the CS- was plain water, which was never paired with electric shock. The dependent variables were derived from Staats' A-R-D theory: attitudinal change (A) and a performance measure of sip-size taken during conditioning trials (D) both confirmed the hypothesis that taste can be an effective CS when the UCS is shock, in contrast to results typically obtained with rats where visual but not taste cues are effective with a shock UCS.     

印象整饰对强迫服从后态度改变的影响

以194名大学生为被试,采用实验室实验法和利克特型态度量表,对Festinger和Carlsmith“强迫服从的认知性后果”实验进行了验证研究,并对个体印象整饰水平—自我监控力的差异对强迫服从后的态度中庸现象的影响作用进行了实验研究。结果表明：（1）自我监控性高低极端组在强迫服从后的态度得分不支持Festinger等实验的结果;（2）个体的印象整饰水平的差异对强迫服从中出现的态度中庸现象有显著影响作用。仅从个体内在的心理因素来解释复杂的社会行为是不够的,我们既要考虑个体自身的因素也要考虑外在环境的作用     

Perceived Symbols of Authority and Their Influence on Compliance1

There are many variables that influence compliance. With regard to individuals making requests of others, Bickman (1974) found that the apparel of the person making the request significantly influenced whether another person complied with the request. This study evaluates other factors such as sex, age, and altruism in compliance. Subjects were involved in a replication of Bickman's dime and parking meter study. Results showed that the dress of the perceived authority not only affected the number of subjects who complied but also the type of compliance, the type of noncompliance, and the latency between request and compliance. Also, older subjects complied significantly more often than younger subjects in the role authority condition.     

Salt taste sensitivity and stimulus volume: sips and drops. Some implications for the Henkin taste test

Various presentation procedures and stimulus volumes were compared in their effect on salt taste sensitivity. For sodium chloride (NaCl) stimuli pipetted onto the tongue, subjects had comparable measured sensitivity to 10 ml and 1 ml volumes but a reduced sensitivity to 0.1 ml volumes. The greatest sensitivity was achieved with 10 ml sipped volumes. Modification of the Henkin dropwise triangular taste test, by increasing the stimulus volumes, increased subjects' sensitivity. Only the 1 ml pipette presentation increased the sensitivity of the Henkin procedure, albeit slightly, to the detection of changes in taste sensitivity, the purpose for which the procedure was actually designed. Such modification did not perturb salivary NaCl levels more than the regular Henkin procedure, so it would not be expected to introduce sensitivity drift.     

Effects of self-monitoring and feedback on residential electricity consumption

Prior research has indicated that frequent feedback could reduce residential electricity consumption by 10% to 15%. However, because feedback was primarily given in written form, this procedure might not be practical. The present study evaluated a potentially more practical feedback procedure during peak-use periods with high electricity consuming households. The study was conducted during the winter in an upper-middle class neighborhood of almost identical, all-electric townhouses (N = 71) that averaged about 170 KWH per day per household for a monthly bill of over $200. Twelve households received daily written feedback. Sixteen households (self-monitoring) were taught to read their outdoor electricity meter and to record KWH used every day. A comparison group was composed of 14 households that had volunteered to participate and 29 others that had only given permission to have their meters read. During a 1-month period that the procedures were in effect, the feedback group reduced consumption by 13% and the self-monitoring group by about 7%. These reductions, relative to the comparison group, were maintained during an early spring 1-month follow-up period and, to a lesser extent, during a 6-week warm spring period. Self-monitoring participants were highly reliable and persistent meter readers. Reductions in electricity use were reported by households to be largely attributable to lowering of the heat thermostat, and large monetary and KWH savings were found. Techniques to make self-monitoring cost-effective important components of the self-monitoring procedure, methods to apply self-monitoring more broadly, and plans to combine behavioral procedures with physical technology are discussed.
