Conditioned taste aversion is enhanced when the unconditioned stimulus is presented in a different context

Using a conditioned taste aversion procedure with rats as the subjects, two experiments examined the effect of presenting a conditioned stimulus (CS saccharin solution) in one context followed by an unconditioned stimulus (US LiCl) in a different context. Experiment 1 showed that animals which received the above-mentioned procedure (Group D) showed a more marked conditioned aversion to the CS than animals which were given both the CS and the US in the same context (Group S). Experiment 2 found that in both Group D and Group S, aversion to the CS increased when the subjects were exposed to the conditioned context after the conditioning. These findings supported the argument that the strength of the CS-US association acquired during conditioning is compared with that of the context-US to determine the magnitude of aversion revealed to the CS.     

No time-stretching illusion when a tone is followed by a noise

A sine tone is perceived as longer when it is preceded by a more intense noise than when presented in isolation. This is the time-stretching illusion. We conducted an experiment where the method of constant stimuli was used to examine whether a tone would also be stretched when it was followed by a noise. The duration of a tone was overestimated when it was preceded by a noise, but not when followed by a noise or when located between two consecutive noises. Moreover, the increasing of the noise intensity (from ?6 to +6 dB) relative to the tone intensity resulted in larger overestimations, but only in the condition where a tone was preceded by a noise. In brief, the duration of a tone is stretched when this tone is preceded by a noise and if this tone is not followed by a noise.     

Marital therapy outcome measured by therapist, client, and behavior change

The present research examined marital therapy outcome, in a sample of 88 couples and 22 therapists, through the use of multidimensional criteria from multiple perspectives. Three paper-and-pencil patient self-report instruments were used to measure different aspects of the couple relationship. In addition, therapist post-therapy ratings and objective observer ratings of the couple behavior during therapy were obtained. Past debates about what the "right" criteria might be for measuring therapeutic change prompted our strategy. Special attention was focused on those criteria that could be classified as "inside" or "outside" of the couple relationship. Data analysis revealed a significant relationship between the couples' and therapists' ratings of improvement in therapy. Additionally, husband and wife negative acts (behaviors) in therapy were also significantly correlated with therapists' ratings of improvement. Both statistically significant and clinically significant criteria were employed to evaluate the therapy outcome. Improvement due to therapy as measured by the three self-report instruments varied from 38% to 58%. These differences appeared to stem from the different kinds of information yielded by the specific tests.     

Marital conflicts in the home when children are present versus absent

Characteristics of marital conflict when children (8-16 years) were present versus absent were compared on the basis of 47 mothers' and fathers' reports during a 15-day period. Mothers described 669 incidents of marital conflict, and fathers described 551 incidents. About two thirds of the conflicts occurred in children's absence. Contrary to predictions, conflicts in which children were present were more negative (e.g., more negative emotions, more destructive conflict tactics) and more often about children than were child-absent conflicts. Although parents may attempt to protect children from conflict exposure, children tend to be exposed to a relatively hostile and emotionally negative subset of the marital conflicts that occur in the home.     

Smiling when distressed: when a smile is a frown turned upside down

This research tested self-regulation and self-presentation as psychological mechanisms that motivate smiling when distressed. In Study 1, participants viewed moderately and intensely distressing, amusing, and neutral videos in social or nonsocial conditions. Smiling when distressed was most prevalent in conditions in which participants reported the greatest emotional distress. Specifically, while viewing distressing videos, men reported experiencing greater overall distress and also smiled more than women, especially in social conditions and while viewing intensely (as opposed to moderately) distressing stimuli. In general, smiling was related to more negative affect while viewing distressing videos but to more positive affect after viewing such stimuli. Study 2 explored raters' social perceptions of participants from Study 1, confirming that people judge distressed smilers as less socially appropriate and less likable than nonsmilers. Findings suggest that although distressed smiling serves a probable self-regulatory function, it may also bear some negative social consequences.     

Contextual therapy: brief treatment of an addict and spouse

The clinical and theoretical applications of contextual therapy for the treatment of drug abuse are presented. A case study illustrates intervention strategies, the therapy process, and a contextual-intergenerational view of drug addiction. Contextual concepts of intergenerational processes, loyalty, fairness, accountability, and trust are defined and applied. Four stages of brief contextual therapy are presented, and the process is examined using examples from transcribed transactions of the therapy sessions. It is suggested that contextual therapy offers conceptual and methodological tools for working with complex situations often involved in drug abuse cases.     

Marital crisis and therapy in their social context

The objective in this paper is to analyze the macro-social trends regarding divorce in Israel and their implications for family therapy. Four macro-social aspects are discussed: legal aspects, demographic trends, single-parenthood, and remarriage. Family therapy strategy must take into account the particular problems of the different varieties of Israeli families, especially the needs of the children, who have no less a stake in the therapy's success than their parents.     

Summation of reinforcement rates when conditioned stimuli are presented in compound

Three experiments used delay conditioning of magazine approach in rats to examine the summation of responding when two conditioned stimuli (CSs) are presented together as a compound. The duration of each CS varied randomly from trial-to-trial around a mean that differed between the CSs. This meant that the rats' response rate to each CS was systematically related to the reinforcement rate of that CS, but remained steady as time elapsed during the CS (Harris & Carpenter, 2011; Harris, Gharaei, & Pincham, 2011). When the rats were presented with a compound of two CSs that had been conditioned separately, they responded more during the compound than during either of the CSs individually. More significantly, however, in all three experiments, the rats responded to the compound at the same rate as they responded to a third CS that had been reinforced at a rate equal to the sum of the reinforcement rates of the two CSs in compound. We discuss the implications of this finding for associative models (e.g., Rescorla & Wagner, 1972) and rate-based models (Gallistel & Gibbon, 2000) of conditioning.     

Preference reversals are diminished when gambles are presented as relative frequencies

Preference reversals are a well-documented example of suboptimal decision making. Typical preference reversals experiments have involved monetary bets presented in probability format. Research on other examples of decision making have shown that irrational or suboptimal choices are diminished or eliminated entirely when the probabilities are presented as relative frequencies (e.g., Gigerenzer & Hoffrage, 1995). The aim of the present experiment was to determine if the way in which information is presented to participants affects participants' preferences. When the options were presented in the standard probability format 59% of participants' preferences were reversed. However, reversals were significantly decreased in the frequency format group, with only 40% of participants' responses being inconsistent. Although preference reversals were not eliminated when the gambles were presented as frequencies they were significantly diminished and may not be such a robust example of irrational decision making after all.

Conjoint marital therapy to enhance anger management and reduce spouse abuse

Abstract

This paper describes a treatment program for couples who mishandle anger and/or are physically abusive. Based on a social learning conception of marital aggression, the treatment endorses the elimination of demonstrations of anger in abusive couples and elaborates upon ways to identify preliminary anger cues, to establish a ground rule that abusiveness is unacceptable, to develop alternative responses that interrupt conflict patterns, and to modify faulty relationship assumptions. Methods to improve couples' problem-solving skills and to enhance their overall enjoyment of the relationship are also proposed as important supplements to the training in anger management skills.     

Invariance of inference time when information was presented in different linguistic formats

Ss read paragraphs varying in syntactic complexity, contiguity of information that was conceptually related, and amount of information relating to quantitative variables. Paragraphs were presented too briefly to allow full reading in many cases. In questions requiring use of the quantitative information, proportion of correct responses was influenced by syntax, contiguity, and number of variables from the paragraph. However, neither syntax nor contiguity influenced latency of correct answers, while number of variables, a factor affecting complexity of the process of answering, did influence correct response latency. The findings confirm and extend earlier results by Kintsch and Monk (1972) and give further support to the proposition that assimilation of information in linguistic input involves storing the semantic content of the message.     

Marital and family therapy supervision: A relational-attachment model

Drawing from attachment theory, this article presents a collaborative marriage and family therapy supervisory model which both advocates and demonstrates a relational and an educational construct for facilitating the supervisory process. Issues concerning cognition and anxiety management are addressed in the context of attachment theory and stages in the supervisory process are identified. Cognitive, emotional, and social development are linked to attachment theory and discussed in the context of supervision.     

Antidepressants and cognitive-behavioral therapy for symptom syndromes

Somatic symptoms are common in primary care and clinicians often prescribe antidepressants as adjunctive therapy. There are many possible reasons why this may work, including treating comorbid depression or anxiety, inhibition of ascending pain pathways, inhibition of prefrontal cortical areas that are responsible for "attention" to noxious stimuli, and the direct effects of the medications on the syndrome. There are good theoretical reasons why antidepressants with balanced norepinephrine and serotonin effects may be more effective than those that act predominantly on one pathway, though head-to-head comparisons are lacking. For the 11 painful syndromes review in this article, cognitive-behavioral therapy is most consistently demonstrated to be effective, with various antidepressants having more or less randomized controlled data supporting or refuting effectiveness. This article reviews the randomized controlled trial data for the use of antidepressant and cognitive-behavior therapy for 11 somatic syndromes: irritable bowel syndrome, chronic back pain, headache, fibromyalgia, chronic fatigue syndrome, tinnitus, menopausal symptoms, chronic facial pain, noncardiac chest pain, interstitial cystitis, and chronic pelvic pain. For some syndromes, the data for or against treatment effectiveness is relatively robust, for many, however, the data, one way or the other is scanty.     

Recall of rapidly presented random chess positions is a function of skill

A widely cited result asserts that experts’ superiority over novices in recalling meaningful material from their domain of expertise vanishes when they are confronted with random material. A review of recent chess experiments in which random positions served as control material (presentation time between 3 and 10 sec) shows, however, that strong players generally maintain some superiority over weak players even with random positions, although the relative difference between skill levels is much smaller than with game positions. The implications of this finding for expertise in chess are discussed and the question of the recall of random material in other domains is raised.     

Learning when reward is delayed: a marking hypothesis

Rats were trained on spatial discriminations in which reward was delayed for 1 min. Experiment 1 tested Lett's hypothesis that responses made in the home cage during the delay interval are less likely to interfere with learning than responses made in the maze. Experimental subjects were transferred to their home cages during the delay interval, and control subjects were picked up but then immediately replaced in the maze. Contrary to Lett's hypothesis, both groups learned. Further experiments suggested that handling following a choice response was the crucial variable in producing learning: No learning occurred when handling was delayed (Experiment 2) or omitted (Experiment 3). One possible explanation for the fact that handling facilitated learning is that it served to mark the preceding choice response in memory so that subjects were then more likely to recall it when subsequently reinforced. In accordance with this interpretation, learning was found to be just as strong when the choice response was followed by an intense light or noise as by handling (Experiment 4). The implication of marking for other phenomena such as avoidance, quasi-reinforcement, and the paradoxical effects of punishment is also discussed.
