A note on the interpretation of the factor pattern of the California Psychological Inventory

The intercorrelation matrix between the scales of the California Psychological Inventory, given in the manual, was factor analyzed. Three factors were extracted and rotated by varimax. The matrix was rescaled, first normalizing the rows, then standardizing the columns to a mean sum of squares of one. Unity was used as a cut-off point for determination of salient loadings. The first two factors were similar to the results reported in a previous Study by Nichols and Schnell. The third factor was interpreted as an independence-dependence dimension.     

“That's Not Analytic”: Theory Pressure and “Chaotic Possibilities” in Analytic Training

Hoping to create my own analytic voice, I experienced complex pressure to conform to the venerated rules of American ego psychology. I could find myself looking over my shoulder, and my training could become saturated with received ideas. Using complex systems theory as a ground, I contrast the constricting pressure to conform that I experienced with three supervisors with the openness that I found with my fourth. I propose that analytic training is a nonlinear, complex developmental process that occurs in a space of “chaotic possibilities” (Glatzer-Levy, 2004)     

Mass Murder: An Analysis of Extreme Violence

Mass murder involves the slaughter of four or more victims by one or a few assailants within a single event, lasting but a few minutes or as long as several hours. More than just arbitrary, using this minimum body count—as opposed to a two- or three-victim threshold suggested by others (e.g., Ressler et al., 1988, Holmes and Holmes, 2001)—helps to distinguish multiple killing from homicide generally. Moreover, by restricting our attention to acts committed by one or a few offenders, our working definition of multiple homicide also excludes highly organized or institutionalized killings (e.g., war crimes and large-scale acts of political terrorism as well as certain acts of highly organized crime rings). Although state-sponsored killings are important in their own right, they may be better explained through the theories and methods of political science than criminology. Thus, for example, the definition of multiple homicide would include the crimes committed by Charles Manson and his followers, but not those of Hitler's Third Reich, or the 9/11 terrorists, despite some similarities in the operations of authority.     

The relationship between change detection and recognition of centrally attended objects in motion pictures

Observers typically detect changes to central objects more readily than changes to marginal objects, but they sometimes miss changes to central, attended objects as well. However, even if observers do not report such changes, they may be able to recognize the changed object. In three experiments we explored change detection and recognition memory for several types of changes to central objects in motion pictures. Observers who failed to detect a change still performed at above chance levels on a recognition task in almost all conditions. In addition, observers who detected the change were no more accurate in their recognition than those who did not detect the change. Despite large differences in the detectability of changes across conditions, those observers who missed the change did not vary in their ability to recognize the changing object.     

Common and distinct factors in decision making under ambiguity and risk: A psychometric study of individual differences

The relation between decision making under ambiguity and risky decision making was examined. In Studies 1 and 2, choices under ambiguity were measured for a large sample receiving an Ellsberg-type Ambiguity-Probability Tradeoff Task. Participants with extreme scores were recruited for Part 2 of each study which consisted of a risky decision making task (Study 1) or a series of decisions under ambiguity in “real life” scenarios (Study 2). Despite a time gap of up to 2 months, individual differences in scores on Part 1 predicted scores on Part 2. In Study 3 participants received in a single session several risky decision making tasks, several measures of decision making under ambiguity, and several personality scales related to uncertainty and decision making style. Taken together, the findings support the existence of a stable dispositional trait to reduce uncertainty in decision making but also task-specific differences related to gains and losses.     

Comparison and representation failures both cause real-world change blindness

Change blindness (CB) occurs when people miss changes across views. Hypothetically, CB would occur if observers failed to represent information about the changing object, but CB would also occur if observers represented and failed to compare information across views, or represented only the pre- or post-change object. For a variety of reasons, previous studies have been unable to determine which of these alternatives contribute to CB in an incidental real-world setting. To address these ambiguities, we conducted two real-world experiments using stimuli that changed on only one feature and tested recognition memory for both the changing feature and a non-changing feature. Participants also provided confidence ratings on recognition responses, allowing us to test whether CB has multiple causes within a single task setting. The results suggest that, in a single real-world setting, CB can be caused by both a failure to represent and a failure to compare information across views.     

Can we still be friends? Resources and barriers to friendship quality after romantic relationship dissolution

Using a social exchange framework, this study examined the influence of resources, satisfaction with resources, and barriers on friendship quality between former dating partners. Three hundred and eighty‐six college students were surveyed regarding their current relationship with their most recent former romantic partner. Results indicated that participants who received more resources reported higher levels of friendship quality with their former partner. Satisfaction with resources moderated the relationship between receipt of resources and friendship quality. Lack of family or friends’ support, involvement in a new romantic relationship, and the use of neglect as a disengagement strategy were all found to be barriers to friendship quality.     

Information integration in price-quality tradeoffs: The effect of missing information

Support for averaging processes in information integration has relied on experimental designs in which the amount of information to be integrated was varied. The usual interpretation is that subjects balance the values of the various stimuli presented on a given trial. An alternative interpretation is that subjects may use their perceptions of the relationship between stimulus dimensions to infer the value of missing information. In the present study, subjects were asked to rate their expected satisfaction with purchases of ground beef on the basis of quality and/or price information. The responses of some subjects appeared to be based on the inference that high prices imply high quality and low prices imply low quality when no quality information is given. Other subjects appeared to assign a constant value to missing information. An averaging model that incorporates inferred as well as presented stimulus values is proposed.
