Understanding of the relationship between seeing and knowing by tufted capuchin monkeys (Cebus apella)

The ability of four tufted capuchin monkeys (Cebus apella) to recognize the causal connection between seeing and knowing was investigated. The subjects were trained to follow a suggestion about the location of hidden food provided by a trainer who knew where the food was (the knower) in preference to a trainer who did not (the guesser). The experimenter baited one of three opaque containers behind a cardboard screen so that the subjects could not see which of the containers hid the reward. In experiment 1, the knower appeared first in front of the apparatus and looked into each container; next, the guesser appeared but did not look into any containers. Then the knower touched the correct cup while the guesser touched one of the three randomly. The capuchin monkeys gradually learned to reach toward the cup that the knower suggested. In experiment 2, the subjects adapted to a novel variant of the task, in which the guesser touched but did not look into any of the containers. In experiment 3, the monkeys adapted again when the knower and the guesser appeared in a random order. These results suggest that capuchin monkeys can learn to recognize the relationship between seeing and knowing. Accepted after revision: 10 September 2001 Electronic Publication     

What to copy: the key factor of observational learning in striped jack (Pseudocaranx dentex) juveniles

Animals in social environments can enhance their learning efficiency by observing the behaviour of others. Our previous study showed that learning efficiency of schooling fish increased through the observation of the behaviour of trained demonstrator conspecifics. The present study aimed to verify the key factor of observational learning by investigating what information is important for social transmission of feeding information. A striped jack (Pseudocaranx dentex) observer was provided with one of the five observation treatments: (a) pellets observation, where pellets were dropped near the aeration in an adjacent tank; (b) responding conspecific observation, where a trained conspecific demonstrator responded to the aeration without food in the adjacent tank; (c) foraging conspecific observation, where a conspecific demonstrator foraged near the aeration in the adjacent tank; (d) nearby pellets observation, where pellets were dropped in a transparent column near the aeration in the observer tank; and (e) foraging heterospecific observation, where a filefish (Stephanolepis cirrhifer) demonstrator foraged near the aeration in the adjacent tank. The response to the aeration in these observers was compared with that of controls who did not observe any behaviour. Only individuals who observed foraging conspecifics showed a response to the aeration after observing. These results suggest that observer fish acquire feeding information not through recognition of prey items or through imitation of the demonstrator, but through the vicarious reinforcement of a conspecific for foraging.     

Comparison of the body-sway characteristics of young adults compared to healthy elderly and elderly with equilibrium disorder

The study compared body-sway characteristics of 380 young adults, 342 generally healthy elderly without disequilibrium disorders, and a group of 33 elderly with disequilibrium disorders. Center of foot pressure (COP) was measured for 1 min. using an Anima's stabilometer G5500 with a data sampling frequency of 20 Hz. Four high reliability measures were used to evaluate body sway (unit time sway, front-back sway, and a left-right sway, and high frequency band power). Unit time sway, left-right sway, and high frequency band power were significantly larger for the group of elderly with disequilibrium disorders, and smaller for the healthy elderly people and young adults, in that order. Front-back sway was significantly larger in the elderly with disequilibrium disorders and healthy elderly than in young adults. The elderly with disequilibrium disorders had a larger and faster sway than young adults as well as the healthy elderly, particularly in the left-right direction. It appears aging was specifically associated with larger influence on the front-back sway.     

United States and Japanese college students' attitudes toward seeking professional psychological help

The purpose of the study was to find how nationality, sex, and past experience of seeking professional psychological services are related to attitudes toward seeking professional psychological help. Three hundred Japanese college students and 300 US college students responded to the Attitudes Toward Seeking Professional Psychological Help (ATSPPH) questionnaire. The ATSPPH consists of four subscales: Need (recognition of need), Stigma Tolerance (the degree of tolerance against stigma associated with help‐seeking action), Openness (interpersonal openness), and Confidence (confidence in mental health professionals). As predicted, past experience of seeking professional psychological service and sex were important predictor variables of performance on the ATSPPH scales. Those who had past experience of seeking professional psychological help had more favourable attitudes toward seeking professional psychological help than those who never consulted psychological professionals. Similarly, in testing the past experience separately with the two nation groups, past experience with seeking professional psychological services was found to be a predictor of the overall attitudes toward seeking professional psychological help among Japanese and US participants. Furthermore, Japanese participants with past experience also showed greater recognition of need for professional psychological help and confidence in psychological health professions than Japanese without past experience. The degree of stigma tolerance associated with help‐seeking behaviour and the tendency of interpersonal openness, however, did not differ between Japanese participants with and without the past experience of seeking professional psychological services. The same results were also found among the US participants. In terms of sex as a predictor variable, females tended to have more positive attitudes toward seeking professional psychological help than males. There was a significant nationality by sex interaction effect. US females had significantly more favourable attitudes than the other three groups, indicating that there was sex difference in help‐seeking attitudes in the US group, but not in the Japanese group. If the sex variable is ignored, Japanese students have less favourable overall attitudes toward seeking professional psychological services than US students. Other results and limitations of the study are discussed.     

Culture and aesthetic preference: comparing the attention to context of East Asians and Americans

Prior research indicates that East Asians are more sensitive to contextual information than Westerners. This article explored aesthetics to examine whether cultural variations were observable in art and photography. Study 1 analyzed traditional artistic styles using archival data in representative museums. Study 2 investigated how contemporary East Asians and Westerners draw landscape pictures and take portrait photographs. Study 3 further investigated aesthetic preferences for portrait photographs. The results suggest that (a) traditional East Asian art has predominantly context-inclusive styles, whereas Western art has predominantly object-focused styles, and (b) contemporary members of East Asian and Western cultures maintain these culturally shaped aesthetic orientations. The findings can be explained by the relation among attention, cultural resources, and aesthetic preference.     

Meta‐analyses of love scales: Do various love scales measure the same psychological constructs?

Abstract: Two statistical meta-analyses synthesized 33 empirical studies which investigated the correlation between relationship satisfaction and two types of love: Erotic Love and Companionate Love, measured by various love scales based on four major theories by Rubin, Lee, Hatfield, and Sternberg. The results drawn by the Hunter-Schmidt method showed that satisfaction was highly correlated with Erotic Love, but that its correlation with Companionate Love was unclear due to heterogeneity in the total sample of the all Companionate Love studies. A moderator analysis indicated a potential moderator, that is, theoretical differences between Lee's Color Theory of Love and the other three theories. The result suggested that a Companionate Love named "Storge" in the Color Theory should not be mixed up with other friendship-style loves defined by other theories as the Storge subscale would measure a different psychological construct.     

Using Acceptance and Commitment Therapy During Methadone Dose Reduction: Rationale,Treatment Description,and a Case Report

Many clients who undergo methadone maintenance (MM) treatment for heroin and other opiate dependence prefer abstinence from methadone. Attempts at methadone detoxification are often unsuccessful, however, due to distressing physical as well as psychological symptoms. Outcomes from an MM client who voluntarily participated in an Acceptance and Commitment Therapy (ACT)–based methadone detoxification program are presented. The program consisted of a 1-month stabilization and 5-month gradual methadone dose reduction period, combined with weekly individual ACT sessions. Urine samples were collected twice weekly to assess for use of illicit drugs. The participant successfully completed the program and had favorable drug use outcomes during the course of treatment, and at the 1-month and 1-year follow-ups. Innovative behavior therapies, such as ACT, that focus on acceptance of the inevitable distress associated with opiate withdrawal may improve methadone detoxification outcomes.     

Comparing Japanese International College Students' and U.S. College Students' Mental‐Health‐Related Stigmatizing Attitudes

This study examined differences between Japanese international college students and U.S. college students on stigma toward people with psychological disorders, stigma tolerance in help seeking, and self‐concealment. Japanese international students had greater stigma toward individuals with psychological disorders than did their U.S. counterparts. No interrelationships between these variables, however, were found in the Japanese international student group. Este estudio examinó las diferencias entre estudiantes universitarios internacionales japoneses y estudiantes universitarios estadounidenses en lo concerniente al estigma hacia las personas con trastornos psicológicos, la tolerancia del estigma al buscar ayuda y la auto‐ocultación. Los estudiantes internacionales japoneses mostraron un mayor estigma hacia los individuos con trastornos psicológicos que sus homólogos estadounidenses. Sin embargo, no se encontró ninguna interrelación entre estas variables en el grupo de estudiantes internacionales japoneses.     

Increasing willingness to experience obsessions: acceptance and commitment therapy as a treatment for obsessive-compulsive disorder

This study evaluated the effectiveness of an 8-session Acceptance and Commitment Therapy for OCD intervention in a nonconcurrent multiple-baseline, across-participants design. Results on self-reported compulsions showed that the intervention produced clinically significant reductions in compulsions by the end of treatment for all participants, with results maintained at 3-month follow-up. Self-monitoring was supported with similar decreases in scores on standardized measures of OCD. Positive changes in anxiety and depression were found for all participants as well as expected process changes in the form of decreased experiential avoidance, believability of obsessions, and need to respond to obsessions. All participants found the treatment to be highly acceptable. Implications and future directions are discussed.
