Ontogeny of the Ponzo illusion: Effects of age,schooling, and environment(1)

Subjects were 384 Moroccan males (age range 6–22 yrs.), divided into 16 equal groups, according to the factorial design: age (4) × schooling (2) × environment (2). Subjects were tested on four Ponzo configurations (differing in contextual information) from Leibowitz et al. (1969), the Ponzo perspective stimulus from Segall et al. (1966), the CEFT from Witkin et al. (1971), and a measure of pictorial depth perception. Individual measures of contact with mass-media and urban life were collected on each subject. Analyses indicated that all main factors of age, schooling, and environment played important, and differing, roles in inducing illusion susceptibility. Piaget's (1969) theory of primary and secondary illusions was found useful in understanding the results of the Ponzo configurations used in the study. Primary illusion configurations were found to be relatively insensitive to experiential variables, and illusion susceptibility decreased with chronological age. In contrast, secondary illusion configurations were affected by many experiential factors, and illusion susceptibility was mediated through perceptual development and pictorial depth perception rather than chronological age. It was concluded that single-factor theories of ontogenetic change in illusion susceptibility were inadequate to explain the complex interactions found in this study.     

Moral Realism,Moral Disagreement,and Moral Psychology

Abstract

This paper considers John Doris, Stephen Stich, Alexandra Plakias, and colleagues’ recent attempts to utilize empirical studies of cross-cultural variation in moral judgment to support a version of the argument from disagreement against moral realism. Crucially, Doris et al. claim that the moral disagreements highlighted by these studies are not susceptible to the standard ‘diffusing’ explanations realists have developed in response to earlier versions of the argument. I argue that plausible hypotheses about the cognitive processes underlying ordinary moral judgment and the acquisition of moral norms, when combined with a popular philosophical account of moral inquiry—the method of reflective equilibrium—undercut the anti-realist force of the moral disagreements that Doris et al. describe. I also show that Stich's recent attempt to provide further theoretical support for Doris et al.'s case is unsuccessful.     

Vulnerability factors in depression: The facets of sociotropy and autonomy

Sociotropy-autonomy (Beck, 1983) describes a set of personality dimensions that relate to an individual's vulnerability to depression. Two recently developed scales, the Sociotropy-Autonomy Scale (Clark & Beck, 1991) and the Personal Style Inventory (Robinset al., 1994), have been developed in order to assess these personality dimensions. Typically, these measures are used in isolation and little published information is available concerning their interrelationship. The present study examined the relationship between the two scales and specified the various factors that emerge when the items of the two scales are integrated. Six hundred fifty-two participants responded to the Personal Style Inventory (Robinset al, 1994) and the Sociotropy-Autonomy Scale (Clark & Beck, 1991). A factor analysis on all of the items of the two scales revealed a five-factor structure (two sociotropy, two autonomy, and one achievement factor). The relationships among depression, the five derived factors, and the original scales developed by Clark and Beck (1991) and Robinset al. (1994) were critically examined. The results are discussed in the context of vulnerability to depression.     

On the detection of time-reversal symmetry breaking by photoemission with circularly polarized light in the high- T c superconductor Bi2212

We argue that that in their recent experiment in which they claim to have found evidence for a time-reversal symmetry broken state, Kaminski et al. () (Nature, 416, p. 610) overlooked small temperature-dependent changes in the superstructure of Bi2212. These subtle changes may manifest themselves by changing the final state configurations of the photoemission process and thus invalidate their ultimate conclusions.     

A cross-cultural replication of attitudes to the physical environment

A replication of Winkel et al.'s (1969) factor analytic study of attitudes to the U.S.A. physical environment was undertaken in Australia. A questionnaire on reactions to the environment was given to 303 South Australian adults. Three factors similar to those identified by Winkel et al. in the U.S.A. were found. However, the method of factor identification used in the present study allowed clearer interpretation and specification of the dimensions. Three additional factors reflecting individual attitudes towards the environment were also distinguished.     

A psychometric examination of the multidimensional perfectionism scale

The Multidimensional Perfectionism Scale (MPS), developed by Frost, Marten, Lahart, and Rosenblate (1990), was constructed using an all female sample at an elite university. This study examined the psychometric properties of the instrument using a more typical sample (n=278) of college students from a large state university and a small liberal arts college, both located in the South. Significant differences were found on the overall MPS score as well as six of the seven subscales between this sample and that of Frostet al. No gender differences were found for any of the MPS scores. Internal reliability was found to be .88 for the total score, with subtests ranging from .57 to .95. Interscore correlations were relatively consistent with the Frostet al. sample except for a negative correlation between the PS subscale and the total score. There was a strong confirmation of the underlying factor structure reported by Frostet al. The overall impression was that the MPS is a psychometrically sound instrument of potential value in studying the construct of perfectionism.     

Social understanding: How does it fare with advancing years?

Until recently, theory of mind abilities have received little attention beyond the childhood years. However, pioneering work carried out by Happé, Winner, and Brownell (1998) has opened the doors on a new and exciting area of research that examines theory of mind abilities in later years. Happé et al. reported that theory of mind performance was superior in the elderly. Yet, in direct contrast to these findings, Maylor, Moulson, Muncer, and Taylor (2002) report a decline in theory of mind abilities with advancing years. We used Happé et al.'s task and, like Maylor et al., found a decline in theory of mind abilities in the elderly. Yet this deficit was related to a decline in fluid abilities. We then examined whether deficits in social understanding in the elderly could also be independent of fluid abilities. We used two new tasks; identifying emotions from still photos and identifying emotions and cognitions from video clips. Again we found a decline in social understanding in the elderly, and in this case, the decline was independent of changes in fluid abilities.     

Children's reports of emotionally laden events: adapting the interview to the child

This study examined the influence of expressive vocabulary and temperament on children's verbal reports about emotionally laden events in different interview conditions. In one of three conditions, 58 children aged between 5 and 7 years were interviewed about a time they had felt happy and a time they had felt scared. The interview conditions were: drawing, in which they were asked to draw and tell; re‐enactment, in which they were asked to re‐enact and tell; and verbal, in which they were simply asked to tell. The principal finding was that, whereas for children in the verbal interview condition expressive vocabulary was associated with the amount of information reported and for children in the re‐enactment condition, temperament had a moderate association with the amount reported, for children in the drawing interview condition, neither temperament nor expressive language was associated with the amount of information reported. Children in the drawing condition reported more information than those in the other two interview conditions. The possible mechanisms underlying these findings and their implications for interviewing children in clinical contexts are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

The aftermath of heresy: a response to Pendery et al.'s (1982) critique of "Individualized Behavior Therapy for Alcoholics"

A point-by-point response is presented to Pendery et al.'s (1982) critique of the study “Individualized Behavior Therapy for Alcoholics (IBTA)”. Two independent, external investigations have critically examined the original records from the IBTA study. The IBTA study compared two different techniques for treating poor-prognosis, chronic alcoholic state hospital patients. It was found that a broad-spectrum behavioral treatment oriented to controlled drinking was a more effective treatment than was the standard hospital treatment program based on conventional wisdom. The Pendery et al. critique gave the appearance of being a refutation by presenting findings for only one group of Ss in a comparative study. In this response, it is shown that the experimental and control Ss were justifiably classified as gamma alcoholics, that Ss were randomly assigned to groups, and that the two groups were comparable in terms of pretreatment characteristics. Moreover, as regards the originally reported 2-yr treatment outcome findings, it is shown that Pendery et al, reported no specific events which were not already documented in the original study records which formed the basis for publications about the IBTA study. Finally, even in terms of long-term outcomes, i.e. mortality rates 10–11 yr after treatment, the experimentally-treated group (20% mortality) continued to fare better than the traditionally-treated group (30% mortality). Ironically, rather than Pendery et al.'s report being a refutation of the original published accounts of the IBTA study, it is concluded that the data reported by Pendery el al. actually strengthen the validity of the original publications. The attack on the IBTA study can be meaningfully viewed as a reflection of the scientific revolution presently underway in the alcohol field. The central impetus for conceptual change in the alcohol field, however, derives less from controlled-drinking research than from the lack of empirical support for conventional wisdom. Ideas are changing because the traditional view no longer inspires progress.     

Structure of PbMnO2.75 determined by electron crystallography

The PbMnO_{3– x} system has a great number of phases with large unit cells for different values of x. In the present work, we study a PbMnO_2.75 phase that has proven too complex to be solved by X-ray powder diffraction. Using electron crystallography, we have determined the positions of all metal atoms without the necessity of using a model as a starting point. The results correspond, within experimental uncertainties, to those obtained by Bougerol et al. (J. Solid State Chem. 169 131 (2002)).     

Children’s causal reasoning: Counterfactual thinking occurs for ‘negative’ outcomes only

Harris, German and Mills (Children’s use of counterfactual thinking in causal reasoning. Cognition, 61 (1996), 223–259), following Mackie, argue that children make explicit use of counterfactual thinking in arriving at causal judgments. They showed that children as young as 3, in explaining simple mishap events, made reference to courses of action that a protagonist had rejected, when that course of action would have prevented the observed outcome. It is hypothesized here that such counterfactual thinking might have been invoked by the ‘negative’ mishaps rather than as part of the causal reasoning process. Although the generation of counterfactuals in explanation was replicated using mishap outcomes such as those used by Harris et al., counterfactual thinking was not evident in children’s explanations of ‘positive’ outcomes. These results undermine the view that a counterfactual thinking process, as indexed by reference to possible actions rejected by a protagonist, is necessary for causal reasoning. Alternative characterizations of the relationship between causals and counterfactuals are discussed.     

Recipient Design in Communicative Pointing

A long‐standing debate in the study of human communication centers on the degree to which communicators tune their communicative signals (e.g., speech, gestures) for specific addressees, as opposed to taking a neutral or egocentric perspective. This tuning, called recipient design, is known to occur under special conditions (e.g., when errors in communication need to be corrected), but several researchers have argued that it is not an intrinsic feature of human communication, because that would be computationally too demanding. In this study, we contribute to this debate by studying a simple communicative behavior, communicative pointing, under conditions of successful (error‐free) communication. Using an information‐theoretic measure, called legibility, we present evidence of recipient design in communicative pointing. The legibility effect is present early in the movement, suggesting that it is an intrinsic part of the communicative plan. Moreover, it is reliable only from the viewpoint of the addressee, suggesting that the motor plan is tuned to the addressee. These findings suggest that recipient design is an intrinsic feature of human communication.     

Teaching a picture language to a non-speaking retarded boy

In recent years numerous operant language training programmes have been designed for teaching both receptive and expressive language to autistic and retarded children (e.g. Bricker and Bricker. 1970a; Bricker and Bricker, 1970b; Lovaas, 1968; Sloane et al, 1968). There have been suggestions that the content of such programmes should be to some extent dictated by the findings of psycholinguists, while the methods be designed along behaviour modification lines (Lynch and Bricker, 1972; Miller and Yoder, 1972). Certainly operant programmes have been shown to produce some improvement of language function in autistic and retarded children (Bricker and Bricker. 1970a; Sloane et al, 1968; Lovaas. 1968; Guesset al, 1968); but the problem of whether all retarded children can be taught some language by these means has not been tackled. Psycholinguists, following Chomsky (Chomsky, 1965) maintain that the development of language in children is dependent on the language acquisition device, or LAD. Unfortunately there are no independent means of determining the presence of LAD in a child, so that relating a child's inability to use language to the absence of LAD becomes a circular argument.It frequently seems to be assumed that, provided no perceptual deficits are present, language acquisition is as difficult in one medium as in another. Individuals who are deaf and retarded have been taught sign language with some success (Berger, 1972; Cornforth et al, 1974), and retarded children who are non-speaking have been taught symbolic languages (Bliss symbols in Vanderheiden et al, 1975; Premack symbols in Hollis and Carrier, 1975, and Hodges, 1976). It is unclear, however, whether those learning symbolic languages, but having no gross physical or perceptual handicap, could have learnt sign language or even spoken language with an equivalent method of training. The present study is a report of a retarded boy with unreliable hearing (which ruled out spoken language), who seemed unable to learn (receptive or expressive) sign language after extensive operant training, but who rapidly acquired a limited symbolic “language” using an identical training method. The symbols used were pictorial representations of the objects (cf. Bliss and Premack symbols).     

Repression-sensitization,gender, and discrepancies in psychobiological reactions to examination stress

Psychobiological responses to examination stress in repressors and sensitizers have rarely been investigated with respect to intraindividual response discrepancies. Furthermore, possible sex differences have rarely been taken into consideration. Therefore the present study investigated if repressors and sensitizers differ in their psychobiological responses to stress and if gender plays a modulating role. 30 and 29 students of both sexes selected from a total group of 96 students were classified as repressors or sensitizers each according to the repression-sensitization-coping-inventory (RSCI, Huwe et al.). State anxiety, heart rate, and cortisol in saliva served as indicators of stress. Sensitizers reported higher state anxiety and showed higher physiological stress responses than repressors. On the intraindividual level sensitizers reported high anxiety as compared to their low cortisol responses whereas repressors reported low anxiety as compared to their high cortisol increases. Gender had no modulating influence on stress responses in repressors and sensitizers.     

What predicts first date success? A longitudinal study of modality switching in online dating

This study uses a longitudinal design to investigate the effects of online dating sites on first date success. Participants were surveyed before their first date with someone from an online dating site (N = 186) and again after meeting their partner in person (N = 94). As part of the survey, they also supplied the e‐mails they had sent to their partner through the dating site so their actual communication could be examined. Findings indicated that first date success was predictable from features of participants' online impressions and relational dynamics. The results are discussed in terms of their theoretical and methodological contributions to the literature on relationship development, as well as their practical implications for online dating sites and users.

A Methodological Study of a Measure of Family Cohesion

Olson, Bell, and Portner ( 11 ) have recently developed a measure of family adaptability and cohesion (The Family Adaptability and Cohesion Evaluation Scales). This study is a critical evaluation of the construction of the cohesion subscale of this instrument. Included is a partial replication of the original work of Olson et al. ( 11 ). Some problems with this subscale and its construction are pointed out, and a subset of the original items is presented and discussed. Some implications of these results for the conceptualization of the nature of family cohesion are also discussed.     

Indicators of Affect Dynamics: Structure,Reliability, and Personality Correlates

Researchers are increasingly interested in the affect dynamics of individuals for describing and explaining personality and psychopathology. Recently, the incremental validity of more complex indicators of affect dynamics (IADs; e.g. autoregression) has been called into question (Dejonckheere et al., 2019), with evidence accumulating that these might convey little unique information beyond mean level and general variability of emotions. Our study extends the evidence for the construct validity of IADs by investigating their redundancy and uniqueness, split-half reliability based on indices from odd-numbered and even-numbered days, and association with big five personality traits. We used three diverse samples that assessed daily and momentary emotions, including community participants, individuals with personality pathology, and their significant others (total N = 1192, total number of occasions = 51 278). Mean and variability of affects had high reliability and distinct nomological patterns to big five personality traits. In contrast, more complex IADs exhibited substantial redundancies with mean level and general variability of emotions. When partialing out these redundancies by using residual variables, some of the more complex IADs had acceptable reliability, but only a few of these showed incremental associations with big five personality traits, indicating that IADs have limited validity using the current assessment practices. © 2020 The Authors.
