Local contrast and Pavlovian induction

Two experiments examined the effects of number and similarity of stimuli on local contrast. In the first experiment, local contrast effects differed in magnitude as a function of the similarity among stimuli; greater positive local contrast appeared when stimuli were less similar, though this effect sometimes reversed for very dissimilar stimuli. In the second experiment, both positive and negative local contrast appeared transiently during the course of training a discrimination including two quite dissimilar stimuli. When two new stimuli were added, both effects reappeared in several cases. The effects remained when the discrimination was rendered more difficult by substituting a new stimulus very similar to one of the original pair. These and other data suggest that local contrast depends on the same factors that produce Pavlovian induction; in the absence of an alternative account, Pavlov's interpretation may be useful in suggesting further research that will help identify the mechanisms involved in both classical and operant discrimination learning.     

The influence of "preparedness" on autoshaping, schedule performance, and choice.

Two groups of experimentally naive pigeons were exposed to an autoshaping procedure in which the response key was mounted on the wall (the conventional location) or on the floor of the chamber. In two experiments, subjects readily responded to the wall key, but floor-key subjects required shaping. A subsequent experiment compared performance of wall- and floor-key groups on an ascending series of fixed-ratio schedule values, resistance to extinction, differential reinforcement of other behavior, and reversal of key assignment. Each experiment was followed by several sessions of fixed-ratio training; the performance of the wall- and floor-key groups was almost identical throughout. In the final experiment, a fixed-ratio requirement could be completed on either or both keys. Birds initially chose the key on which they had responded during the preceding (reversal of key assignment) experiment. However, within a few sessions both groups showed almost exclusive preference for the floor key. Preference for a key located on the floor may follow from the fact that pigeons are ground feeders and may thus be more "prepared" to peck the floor than to peck a wall. However, autoshaping, under the conditions prevailing here, occurred much more readily to the wall key, suggesting that pecking a vertical surface is more highly prepared. Difficulties in determining relative preparedness seem moot, however, given the lack of between-group differences in the intervening experiments. It is thus unlikely that schedule performances critically depend upon the specific operant response involved.     

Medicaid: A potential source of revenue for special education

Currently, over 4.3 million children are receiving special services within the nation's schools because of physical, developmental, and educational disabilities. It is estimated that twice this number would benefit from special education services. Public Law 94–142, the Education for the Handicapped Act, offered the first real opportunity for many children with disabilities to receive special health and educational services. Public schools have become a primary setting for provision of services to these children, however, many states have encountered difficulty in procuring funding. One federally mandated source of revenue is the Medicaid program. In the fall of 1991, all state Medicaid and special education programs were asked to provide information concerning current or planned use of Medicaid funds for special education services. Responses were received from 36 states. Only 19 states reported using Medicaid funding in any capacity, and of these, only four required schools to bill Medicaid for services rendered. The majority of these programs are in the pilot stages of development. Special education services covered by Medicaid vary widely, as do reimbursement mechanisms. All 19 states allow Medicaid coverage for speech, physical, and occupational therapy. Only about half of those states provide allowances for diagnostic evaluation and assessment, while coverage for psychological services is provided by three-fourths of those states, and EPSDT screens by half of the states. Only two programs had been evaluated formally at the state and/or federal level. Medicaid remains a largely untapped source of revenue that could be used to help fund services for disabled children.     

Toward a theory of intrinsically motivating instruction

First, a number of previous theories of intrinsic motivation are reviewed. Then, several studies of highly motivating computer games are described. These studies focus on what makes the games fun, not on what makes them educational. Finally, with this background, a rudimentary theory of intrinsically motivating instruction is developed, based on three categories: challenge, fantasy, and curiosity. Challenge is hypothesized to depend on goals with uncertain outcomes. Several ways of making outcomes uncertain are discussed, including variable difficulty level, multiple level goals, hidden information, and randomness. Fantasy is claimed to have both cognitive and emotional advantages in designing instructional environments. A distinction is made between extrinsic fantasies that depend only weakly on the skill used in a game, and intrinsic fantasies that are intimately related to the use of the skill. Curiosity is separated into sensory and cognitive components, and it is suggested that cognitive curiosity can be aroused by making learners believe their knowledge structures are incomplete, inconsistent, or unparsimonious.     

Cross-cultural effects of parent warmth and control on aggression and rule-breaking from ages 8 to 13

We investigated whether bidirectional associations between parental warmth and behavioral control and child aggression and rule-breaking behavior emerged in 12 cultural groups. Study participants included 1,298 children (M = 8.29 years, standard deviation [SD] = 0.66, 51% girls) from Shanghai, China (n = 121); Medellín, Colombia (n = 108); Naples (n = 100) and Rome (n = 103), Italy; Zarqa, Jordan (n = 114); Kisumu, Kenya (n = 100); Manila, Philippines (n = 120); Trollhättan/Vänersborg, Sweden (n = 101); Chiang Mai, Thailand (n = 120); and Durham, NC, United States (n = 111 White, n = 103 Black, n = 97 Latino) followed over 5 years (i.e., ages 8–13). Warmth and control were measured using the Parental Acceptance-Rejection/Control Questionnaire, child aggression and rule-breaking were measured using the Achenbach System of Empirically-Based Assessment. Multiple-group structural equation modeling was conducted. Associations between parent warmth and subsequent rule-breaking behavior were found to be more common across ontogeny and demonstrate greater variability across different cultures than associations between warmth and subsequent aggressive behavior. In contrast, the evocative effects of child aggressive behavior on subsequent parent warmth and behavioral control were more common, especially before age 10, than those of rule-breaking behavior. Considering the type of externalizing behavior, developmental time point, and cultural context is essential to understanding how parenting and child behavior reciprocally affect one another.     

Regulation and standards for psychoanalysis: The place of the Other in psychoanalysis and its teaching

In numerous Western countries, psychotherapies have come under increasing governmental regulation. A more recent development is the increasing scrutiny given to psychoanalysis in the United Kingdom, in France, and in the United States. This paper examines a particular document that was created by four professional psychoanalytic organizations that are based in the United States. The document called Standards of Psychoanalytic Education aims to develop criteria that would guide accreditation and the organization of psychoanalytic institutes. The document is part of a set of concerns and actions related to the state regulation of psychoanalytic practice, its professional status, and the protection of those who seek its services. The essay examines the putative theoretical neutrality of this document by unfolding its tenets in terms of Lacanian psychoanalysis, a school of psychoanalysis that would take exception to many of the ideas suggested in the document's template for psychoanalytic education. The paper follows one line of argumentation throughout: what is the place of the Social Field, the Symbolic Other, within psychoanalytic process and as a recourse for professional legitimization that stands outside of psychoanalysis? As a practice of particularity, what relation does the discipline bear to other mental health fields and to the norms and knowledge systems of the mental health professions? Using a Lacanian orientation, two senses of the Other are discussed, and the specificity of psychoanalysis is asserted. This specificity is contrasted with some of the goals and constraints that are introduced by current approaches to regulation.      

Brands as intentional agents framework: How perceived intentions and ability can map brand perception

Building on the Stereotype Content Model, this paper introduces and tests the Brands as Intentional Agents Framework. A growing body of research suggests that consumers have relationships with brands that resemble relations between people. We propose that consumers perceive brands in the same way they perceive people. This approach allows us to explore how social perception theories and processes can predict brand purchase interest and loyalty. Brands as Intentional Agents Framework is based on a well-established social perception approach: the Stereotype Content Model. Two studies support the Brands as Intentional Agents Framework prediction that consumers assess a brand's perceived intentions and ability and that these perceptions elicit distinct emotions and drive differential brand behaviors. The research shows that human social interaction relationships translate to consumer–brand interactions in ways that are useful to inform brand positioning and brand communications.     

Brands as intentional agents: Our response to commentaries

We are grateful for the stimulating and hospitable welcome to us as guests in consumer psychology. As sojourners, we share a keen interest, but know that we come to visit without knowing the territory intimately. Granted, Chris Malone is an experienced, senior marketing practitioner who now owns a research-based consulting firm with a particular interest and specialization in this area. In addition, Nicolas Kervyn, trained as an experimental social psychologist, has worked and consulted in marketing. Susan Fiske, trained as an experimental social psychologist, had kibitzed in consumer psychology since she first served on the JCP board as an assistant professor. However, none of us has imperialist ambitions in consumer psychology. We are happy nonetheless to offer our framework as what seems to us a potentially useful complement to prior and ongoing related work. These exceptionally thoughtful commentaries broaden and inform our framework (Kervyn, Fiske, & Malone, 2012--this issue). In return, we offer some responses regarding our own view of the Brands as Intentional Agents Framework (BIAF), its parent, the Stereotype Content Model (SCM), and relationships with the commentators’ own contributions.     

Health Related Quality of Life After Gastric Bypass Surgery

The majority of studies which have evaluated health related quality of life are limited in the duration of follow up. The objective of this study was to prospectively conduct an evaluation using a repeated cross sectional analysis of separate patient cohorts who were up to four years after gastric bypass surgery. Adult Roux-en-Y gastric bypass patients were recruited to the study. All patients were requested to complete a general health status questionnaire, the Short Form-36 (SF-36), before surgery or at their post operative out patient follow up visits. Patient weight was documented at each follow up visit. A cross sectional analysis was performed to evaluate SF-36 scores in each annual cohort. Data are reported as mean +/− S.D. Three-hundred-eight patients completed at least one SF-36 assessment [Initial assessment at the time of surgery, time 1, n = 245, 1y n = 149, 2y n = 70, 3y n = 59, 4y n = 61]. The SF-36 scores were greater (p < 0.05) in each of the separate post surgery cohorts for physical functioning, role limitations due to physical health, social functioning, pain, vitality, general health and the physical component summary (PCS) scores. While not comparing changes in scores within individuals over time, these data suggest early improvement especially in the physical dimension of health related quality of life. In this analysis, this finding was also observed in each of the separate cohorts up to 4 years after gastric bypass surgery.
