The infant's theory of self-propelled objects

"Theory of mind" is treated as a modular component of human social behavior and an attempt is made to find the origins of this component in the perception of the infant. According to the theory I describe here, the infant assigns a high priority to changes in motion and divides the world into two kinds of objects on the basis of this criterion: those that are and those that are not self-propelled. How the infant perceives these two kinds of objects is described by four basic assumptions. First, when the state of motion of a nonself-propelled object is changed by another object, the infant's principal hard-wired perception is causality; when a self-propelled object changes its motion without assistance from another object the infant's principal hard-wired perception is intention. Second, if two self-propelled objects are related in a special way--a relation called the BDR sequence--the infant perceives not only intentional movement but also one object as having the goal of affecting the other object. Third, the BDR sequence has a more powerful consequence: the infant perceives that the affected object intends to reciprocate. Fourth, the infant expects that reciprocation will preserve valence (not form), where valence is formulated either as the preservation/denial of liberty, or as an aesthetic response.     

When representations conflict with reality: the preschooler's problem with false beliefs and "false" photographs

It has been argued that young preschoolers cannot correctly attribute a false belief to a deceived actor (Wimmer & Perner, 1983). Some researchers claim that the problem lies in the child's inadequate epistemology (Chandler & Boyes, 1982; Wellman, 1988); as such, it is specific to the child's theory of mind and no such problem should appear in reasoning about nonmental representations. This prediction is tested below in the "false photograph" task: here an actor takes a photograph of an object in location X; the object is then moved to location Y. Preschool subjects are asked: "In the picture, where is the object?" Results indicate that photographs are no easier to reason about than are beliefs. Manipulations to boost performance on the photograph task proved ineffective. Further, an explanation of the failure as a processing limitation having nothing to do with the representational nature of beliefs or photographs was ruled out. It is argued that young children's failure on the false belief task is not due to an inadequate epistemology (though they may have one) and is symptomatic of a larger problem with representations.     

Performance of criminal psychopaths on selected neuropsychological tests

Screening batteries of standard neuropsychological tests were administered to 2 different samples (Ns = 90 and 167) of male prison inmates. Scores on the revised Psychopathy Checklist were used to divide inmates in each sample into high, moderate, and low psychopathy groups. There were no group differences in test performance in either of the samples, even when the effects of self-reported psychopathology and substance abuse were taken into account. The overall prevalence of both test-specific and global neuropsychological impairment was low and did not vary significantly across the 3 groups. The results provide no support for traditional brain-damage explanations of psychopathy.     

Film-induced negative affect triggers overeating in restrained eaters

We tested the effects of film-induced negative affect (i.e., exposure to a frightening film) in 60 women classified as either restrained or unrestrained eaters on the basis of their responses to the Revised Restraint Scale (Herman & Polivy, 1980). Exposure to the frightening film, in contrast to a neutral film, was associated with increases in anxiety, sadness, and anger. High restraint subjects exposed to the frightening film ate more than did equally restrained subjects exposed to a neutral film or low restraint subjects exposed to either film. Thus, negative affect triggered overeating among restrained eaters. Although unrestrained eaters exposed to the frightening film ate less than those who viewed the neutral film, this difference was not statistically significant. These results suggest that negative affect may prompt overeating in persons who attempt to restrict their caloric intake.     

Peer-group association and adolescent tobacco use

Mosbach & Leventhal (1988) examined the relation of cigarette smoking to peer-group identification in rural Wisconsin adolescents. They found that among dirts (problem-prone youth), regulars (average youth), hot-shots (good social or academic performers), and jocks (athletes), youth most likely to smoke were dirts and hot-shots. We performed a replication with a Southern California cohort and also for use of smokeless tobacco. We hypothesized that jocks would be the main users of smokeless tobacco. We identified the same groups and an additional one, skaters (skateboarders or surfers). As Mosbach & Leventhal found, cigarettes were used most by dirts. Contrary to their results, but consistent with other research, we found that hot-shots were least likely to smoke. Contrary to our prediction, we found that skaters and dirts were more likely to use smokeless tobacco than were jocks. Our data show that both tobacco forms are used by problem-prone youth.     

Depressive personality: reliability, validity, and relation to dysthymia

The reliability and validity of Schneider's (1958) construct of depressive personality was evaluated in a sample of 177 outpatients, who were administered structured diagnostic and family history interviews, an extensive battery of inventories, and a 6-month follow-up assessment. The criteria for depressive personality had moderate to good interrater reliability, internal consistency, and test-retest stability, and the assessment of depressive personality traits was not influenced by patients' clinical states. In addition, preliminary support for the convergent and discriminant validity of the depressive personality construct was obtained. Although there were significant relations between the depressive personality and Diagnostic and Statistical Manual of Mental Disorders (3rd ed. and rev. 3rd ed.; American Psychiatric Association, 1980, 1987) diagnoses of dysthymia, the depressive personality was not entirely subsumed by existing mood disorders.     

The nature of aspiration in psychotherapy

This paper underscores the importance of aspiration as an active, progressive striving toward goals. Aspiration is often borne out of new experiences with new objects that differ from the patient's archaic objects. Patients who take inventory of their aspirations start to understand how they consciously and unconsciously work toward or ward off the attainment of goals. Self-discrepancy approaches (e.g., Jacobson, 1964; Schafer, 1967; Blos, 1974; Higgins, 1987) emphasizing the gap between the patient's present self-experience and the ideal self are especially useful in understanding how aspiration is facilitated or stymied. Aspirations may signal shifts in self-esteem. The patient who risks wanting more or wanting to be more has begun to alter the static view of the self. Aspiration facilitates the patient's imaginative, visualizing capacities as he or she focuses on foreseeing future possibilities.     

Phantom cotherapist: Treatment of a suicidal Arab by a Jewish therapist

A case study is presented of the treatment of an Arab coed by a Jewish trainee, and a phantom cotherapist using a modified dialectical therapeutic approach. Its effect on the treatment process and outcome, and on the therapist is discussed.     

Concurrent Use of Cigarettes,Alcohol, and Coffee1

The interrelationships between cigarette, alcohol, and coffee use were examined in 307 U.S. army trainees and 304 U.S. enlisted army personnel. Usage patterns indicated distinct gender differences in this occupational setting. Among women, cigarette use and alcohol consumption were positively correlated; whereas for men, cigarette and coffee use were positively related. For both males and females, alcohol and coffee use were only weakly correlated. As demonstrated in other studies, nonsmokers showed a consistent pattern of abstention from coffee and alcohol or moderate alcohol use.     

Group Commitment and Resource Conservation: Two Field Experiments on Promoting Recycling1

Two experiments evaluated the effect of commitment on paper recycling. Using an ABA design, Experiment 1 asked 24 individuals in a retirement home to sign a 4-week group commitment pledge to recycle paper. During this intervention, the subjects recycled 47% more paper than they had during baseline. They continued to recycle at this level during a 4-week follow-up period, when the group commitment was removed. Experiment 2 evaluated the relative effectiveness of group commitment, individual commitment, and token reinforcers on paper recycling in a college dormitory. The students in all three experimental conditions recycled from three to five times more paper than those in the control group during the 4-week intervention. However, in the 3-week follow-up period, when the treatments were removed, only the individually committed subjects continued to recycle significantly more paper than the controls.
