The effects of errorless learning and backward chaining on the acquisition of Internet skills in adults with developmental disabilities

An important area in the learning and development of individuals with disabilities is the acquisition of independent, age-appropriate leisure skills. Three adults with autism and mental retardation were taught to access specific Internet sites using backward chaining and most-to-least intrusive prompting. The number of independent steps completed in the task analysis increased following training.     

Discrepancy detection in the retrieval-enhanced suggestibility paradigm

Retrieval-enhanced suggestibility (RES) refers to the finding that immediately recalling the details of a witnessed event can increase susceptibility to later misinformation. In three experiments, we sought to gain a deeper understanding of the role that retrieval plays in the RES paradigm. Consistent with past research, initial testing did increase susceptibility to misinformation – but only for those who failed to detect discrepancies between the original event and the post-event misinformation. In all three experiments, subjects who retrospectively detected discrepancies in the post-event narratives were more resistant to misinformation than those who did not. In Experiments 2 and 3, having subjects concurrently assess the consistency of the misinformation narratives negated the RES effect. Interestingly, in Experiments 2 and 3, subjects who had retrieval practice and detected discrepancies were more likely to endorse misinformation than control subjects who detected discrepancies. These results call attention to limiting conditions of the RES effect and highlight the complex relationship between retrieval practice, discrepancy detection, and misinformation endorsement.     

Changing plans: Dynamic inconsistency and the effect of experience on the reference point

This article presents a new test of a principle of decision making calleddynamic consistency. This principle was tested in an experiment in which participants were asked to make decisions about a second gamble within a sequence of two gambles. Participants were first asked to make a planned choice about the second gamble. The planned choice was madebefore the first gamble was played and was conditioned on the anticipated outcomes of the first gamble.After the first gamble was played, the same participants were asked to make a final choice about the second gamble, conditioned on the experienced outcome of the first gamble. The results showed that participants’ final choices were frequently inconsistent with their plans, even when the anticipated and experienced outcomes were identical. These inconsistencies occurred in a systematic direction. Experiencing an anticipated gain resulted with a change toward risk aversion, and experiencing an anticipated loss resulted in a change toward risk seeking. These results are explained in terms of the effect of actual experience on the reference point used for the evaluation of the decision problem.     

Father and Son: Freud Revisits his Oedipus Complex in <Emphasis Type="Italic">Moses and Monotheism</Emphasis>

In this paper, I propose to understand Freud on his own terms and within his social, intellectual and psychological context. It is my hope that such an understanding will contribute in turn to our understanding of some of the sources of the creative process. Were it not for his fame, Freud's views on religion, history and art, would at best be but a footnote to these subjects. My contention is that Freud's writings on these subjects can contribute more to our understanding of Freud, the person, than they do to some of the subjects he is writing about. Toward this end I will focus on two of Freud's works, written more than 30 years apart, his early Moses of Michelangelo and his late-life work Moses and Monotheism, which reflect the considerable changes in Freud's thinking.     

Child, family, and childcare predictors of delayed school entry and kindergarten retention among linguistically and ethnically diverse children

Concern about kindergarten retention is on the rise within the current climate of high-stakes testing and escalating kindergarten expectations. Kindergarten retention has been linked in previous research to various risk factors such as poverty, low maternal education, single parent status, minority status, English language learner (ELL) status, and male gender. However, these factors are also associated with poor school readiness and low kindergarten performance--the very reasons children are retained in the 1st place. This study teases apart unique and combined predictors of delayed entry into kindergarten and kindergarten retention with a large (n = 13,191) ethnically diverse, at-risk sample of children. Delayed kindergarten entry was rare for this sample but more likely among boys, native English speakers, those with poorer school readiness, less maternal education, and greater resources, and those who attended childcare rather than public school prekindergarten (pre-K) at age 4 years. Boys were more likely to be retained in kindergarten, but only because of their poorer school readiness. After strong effects for age 4 school readiness were controlled, only poverty, ELL status, and preschool program attendance predicted retention. ELL students were less likely to be retained than were native speakers, and those who attended public school pre-K programs were less likely to be retained, compared with those in childcare at age 4 years. After controlling for children's actual performance in kindergarten their 1st time, Caucasian children and children with lower language and social skills at age 4 years were more likely to repeat kindergarten.     

The six most essential questions in psychiatric diagnosis: a pluralogue part 1: conceptual and definitional issues in psychiatric diagnosis

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM - whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.     

Contextualizing experience

This paper extends the discussion of Luke and Banerjee published in an earlier issue of this Journal by suggesting that psychologists studying the effects of stressful experiences on a later outcome do not always acknowledge the possibility that the experience might be correlated with conditions that are necessary for the outcome. This essay argues that the victims of a stressful event are not a random sample of the population and often belong to gender, class, or ethnic groups during particular historical eras that contribute to the outcome. The properties of these groups represent causal patterns that should replace the usual practice of examining the relation between a single independent and dependent variable.
