Predictors of Entry into Age-Discordant Relationships Among Adolescent Girls

Teenage girls in age-discordant relationships remain of concern for healthy development and well-being. We examine whether factors from several sociological frameworks—self-esteem, deviance, social ecology, family cohesion, and religious involvement—predict entry into such relationships. With longitudinal data on 1,537 adolescent girls, we use structural equation modeling to assess risk and protective factors by age group. Results indicate that few social factors predict entry to such relationships; only religious involvement for the youngest adolescents and self-esteem for middle adolescents predict entry. While adolescent girls who date older males are largely like their peers, any impact of social factors may vary by the developmental stage that adolescent girls occupy.     

False memories of fabricated political events

In the largest false memory study to date, 5,269 participants were asked about their memories for three true and one of five fabricated political events. Each fabricated event was accompanied by a photographic image purportedly depicting that event. Approximately half the participants falsely remembered that the false event happened, with 27% remembering that they saw the events happen on the news. Political orientation appeared to influence the formation of false memories, with conservatives more likely to falsely remember seeing Barack Obama shaking hands with the president of Iran, and liberals more likely to remember George W. Bush vacationing with a baseball celebrity during the Hurricane Katrina disaster. A follow-up study supported the explanation that events are more easily implanted in memory when they are congruent with a person's preexisting attitudes and evaluations, in part because attitude-congruent false events promote feelings of recognition and familiarity, which in turn interfere with source attributions.     

Attitudes about memory dampening drugs depend on context and country

When people take drugs such as propranolol in response to trauma, it may dampen their bad memories – tempering recall of a traumatic event. We examined people's attitudes toward these drugs. Americans and New Zealanders read about a hypothetical assault inserting themselves into a scenario as a victim attacked while serving on a peace keeping mission (soldier role) or while walking home from a job as a restaurant manager (civilian role). Then they told us whether they should receive a memory dampening drug, and whether they would want to take a memory dampening drug. Subjects were negatively disposed towards a memory dampening drug, but Americans who adopted the soldier role were more in favor of having access to the drug than those who adopted the civilian role. We discuss the implications of these findings in relation to an increasing trend in ‘cosmetic neurology’, medicating with the goal of enhancement, rather than therapy.

‘Unconscious transference’ can be an instance of ‘change blindness’

Three experiments investigated the role of ‘change blindness’ in mistaken eyewitness identifications of innocent bystanders to a simulated crime. Two innocent people appeared briefly in a filmed scene in a supermarket. The ‘continuous innocent’ (CI) walked down the liquor aisle and passed behind a stack of boxes, whereupon the perpetrator emerged and stole a bottle of liquor, thereby resulting in an action sequence promoting the illusion of continuity between perpetrator and innocent. The ‘discontinuous innocent’ (DI) was shown immediately afterward in the produce aisle. Results revealed that: (1) more than half of participants failed to notice the change between the CI and the perpetrator, (2) among those who failed to notice the change, more misidentified the ‘CI’ than the ‘DI’, a pattern that did not hold for those who did notice the change. Participants were less likely to notice the change when they were distracted while watching the video. Copyright © 2007 John Wiley & Sons, Ltd.     

The revelation effect for autobiographical memory: A mixture-model analysis

Participants provided information about their childhood by rating their confidence about whether they had experienced various events (e.g., “broke a window playing ball”). On some trials, participants unscrambled a key word from the event phrase (e.g., wdinwo—window) or an unrelated word (e.g., gnutge—nugget) before seeing the event and giving their confidence ratings. The act of unscrambling led participants to increase their confidence that the event occurred in their childhood, but only when the confidence rating immediately followed the act of unscrambling. This increase in confidence mirrors the “revelation effect” observed in word recognition experiments. In the present article, we analyzed our data using a new signal detection mixture distribution model that does not require the researcher to know the veracity of memory judgments a priori. Our analysis reveals that unscrambling a key word or an unrelated word affects response bias and discriminability in autobiographical memory tests in ways that are very similar to those that have been previously found for word recognition tasks.     

HEURISTICS FOR DETERMINING THE OPTIMAL INTERVAL BETWEEN CHECKUPS

Abstract –How often should one check on a system that is at risk for some malfunction? The optimal interval between inspections depends on the likelihood of malfunction, the cost of inspection, and the cost of treatment We develop a mathematical expression for the optimal inspection interval as a function of these parameters and then an approximation for that expression The approximation indicates that as the risk increases or the ratio of inspection to disease cost decreases by a factor of n, the inspection interval should be reduced by n1/2 We also report an experiment indicating that subjects who generate optimal inspection intervals use examples as anchors and then perform adjustments for variations in risk and cost factors However, they do not approximate the appropriate square-root adjustment rule The observed anchor-and-adjust process suggests that normative recommendations may serve as influential benchmarks, even if they are not adhered to directly.     

Since the eruption of Mt. St. Helens,has anyone beaten you up? Improving the accuracy of retrospective reports with landmarkevents

When people are questioned about past experiences, it is common for eventsto be reported as happening more recently than they actually did. One technique for reducing the instances of this “forward telescoping” is tested in the current research: It involves the provision of landmark events that can clearly mark the beginning of the reference period. Such atechnique was shown to reduce the telescoping problem in five experiments, involving 1, 694 subjects. The landmark event used in two of the studies was the first major eruption of Mt. St. Helens, and use of this event was shown to significantly reduce the incidence of forward telescoping of crime victimizations. Asking subjects to provide their own personal landmarks had similar beneficial effects. Finally, a more usual public landmark event, New Year’s day, substantially reduced forward telescoping. At least part, but not all, of the benefit of landmark events appears to be due to their being dated rather precisely.     

A front end to a theory of picture recognition

We describe the results of four picture-recognition memory experiments in which we systematically manipulated four variables: stimulus duration, stimulus contrast, the duration of a blank gap between successive presentations of the same stimulus, and the presence or absence of a noise mask that immediately followed stimulus offset. The patterns of obtained data confirmed a simple extension of a theory previously used to account for digit recall data. This theory consists of a low-pass linearfilter front end that generates a sensory response from the physical stimulus, followed by an informationsampling process whose instantaneous sampling rate is based in part on the sensory response magnitude. The data confirm both qualitative and quantitative theoretical predictions, some of which were previously untestable in digit recall tasks because of ceiling effects that were not present in our picturerecognition tasks. We describe the role of our theory within the broader family of picture-memory theories, and we briefly discuss our theory’s unification of two salient facets of visual behavior: information acquisition on the one hand, and phenomenological appearance on the other hand.     

Measuring dissociation: comparison of alternative forms of the dissociative experiences scale

The dissociative experiences scale (DES), developed by Bernstein and Putnam (1986), is commonly used to measure dissociation in clinical populations. It is often used with nonclinical populations to assess how levels of dissociation covary with other psychometric measures. When it is used with nonclinical populations, problems arise because the resulting scores can show severe floor effects and often are highly skewed. To remedy these problems, we developed alternative ways of measuring self-reported dissociative experiences. A form of the DES in which people were required to rate how often they have each of 28 experiences compared with other people was superior in avoiding problems of floor effects and skewness. We discuss situations in which this alternative, which we call DES C, is preferred.     

Postdictions of 20-year predictions about the state of computer technology in psychology (and one or two other matters)

I make three general points. First, I argue that the conjunction of two important characteristics prevents computer technology from becoming tedious and boring. Second, I discuss the fate of several “postdictions” of what we would have predicted about 1990 computer technology 20 years ago. Third, I discuss the degree to which computer technology drives research rather than the other way around.
