Should Kohlberg's cognitive developmental approach to morality be replaced with a more pragmatic approach? Comment on Krebs and Denton (2005)

Krebs and Denton (2005) proposed that Kohlberg's cognitive developmental approach to morality be replaced by a pragmatic approach more relevant to everyday social behavior and the cooperative moral orders of society. Although the Krebs and Denton article raises some legitimate questions, their proposal is at best premature and provokes some serious concerns. Their starting point, that Kohlberg's model of morality is inadequate, is an evaluation shared by many neo-Kohlbergians. Before the cognitive developmental approach is replaced, however, important contributions (e.g., Rest's schema interpretation of the stages) toward refining or improving the approach must be adequately considered. Evidence suggests that Krebs and Denton may have underestimated relations between moral judgment stages and social behavior, including sudden behavior in emergency situations.     

Hemispheric dissociation of the involvement of NOS isoforms in memory for discriminated avoidance in the chick

Previous research has indicated a role for both the neuronal (nNOS) and endothelial (eNOS) nitric oxide isoforms in memory formation. In addition, two distinct periods of activity of nitric oxide activity, dissociated by hemispheric localization, are implicated following passive avoidance training in the chick. In the present study, we trained black Australorp-white Leghorn chicks on a color discrimination avoidance task. Diphenyleneiodonium chloride (1 microM) or N-propyl-l-arginine (50 microM) was administered into either the left or right hemisphere of the chick brain in an attempt to differentiate the effects of inhibiting eNOS or nNOS, respectively. The memory loss previously observed following administration of diphenyleneiodonium chloride between 10 and 20 min posttraining was found to be lateralized to the right hemisphere, although administration of this agent into the left hemisphere around the time of training was also amnestic. In contrast, N-propyl-l-arginine caused memory loss only when administered to the left hemisphere around the time of training. These findings suggest that activation of both eNOS and nNOS isoforms may be essential for long-term memory consolidation of this task. Further, these two periods of activity are defined temporally and by hemisphere localization, although confirmation with more selective inhibitors when they become available is advised.     

Who needs control? A cultural perspective on the process of compensatory control

Compensatory control theory (CCT) provides a framework for understanding the mechanisms at play when one's personal control is challenged. The model suggests that believing the world is a structured and predictable place is fundamental, insofar as it provides the foundation upon which people can believe they are able to exert control over their environment and act agentically towards goals. Because of this, CCT suggests, when personal control is threatened people try to reaffirm the more foundational belief in structure/predictability in the world, so that they then have a strong foundation to reestablish feelings of personal control and pursue their goals. This review seeks to understand how the basic assumptions of these compensatory control processes unfold in different cultural contexts. Drawing on research and theorizing from cultural psychology, we propose that cultural models of self and agency, culturally prevalent modes of control, and culture-specific motivations all have implications for compensatory control processes. Culture determines, in part, whether or not personal control deprivation is experienced as a threat to perceiving an orderly world, how/whether individuals respond to low personal control, and the function that responses to restore a sense of order in the world serve. A theoretical model of compensatory control processes across cultures is proposed that has implications for how people cope with a wide range of personal and societal events that potentially threaten their personal control.     

Processing idioms with multiple meanings

Three experiments are presented that examine understanding of idioms with one or more meaning. The results of Experiment 1 showed that subjects took longer to read and make paraphrase judgments for idioms when both their idiomatic and literal meanings are intended than it did to comprehend idioms meant only literally or idiomatically. In Experiments 2 and 3, subjects were faster at making phrase classification judgments for idioms with several different nonliteral interpretations than they were to make the same judgments for idioms with only one idiomatic interpretation. These findings suggest that idioms with more entries in the mental lexicon are accessed faster because it is more likely that one of their meanings will be encountered in a short time. The data overall support the idea that idioms are represented differently depending on their number of associated meanings.This research was supported by a Faculty Research Grant from the University of California, Santa Cruz.

On the process of understanding idioms

This paper presents arguments against the idea that people normally analyze the literal meanings of idiomatic expressions during understanding. A number of empirical studies are reviewed which suggest that people do not compute the literal interpretations of idioms either before or simultaneous to comprehending their figurative meanings. This seems particularly true given that many idiomatic expressions do not have well-defined literal meanings. Finally, it is suggested that although idioms are understood directly as if single words, it is premature to accept the idea that all idioms are represented with equal status in the lexicon.Preparation of this paper was supported by a Faculty Research Grant from University of California, Santa Cruz.

Sex differences in route learning by children.

Differences between men and women have been reported with respect to route-learning, but sex differences in children on these and related tasks have not been found. In this study, 51 children ages 5 to 12 years were required to learn a route on a map to criterion and then asked to recall landmarks on that route. Boys made significantly fewer errors and took less time and fewer trials to reach criterion in learning the route, and girls recalled more landmarks than boys. Significant main effects for age were also noted on all measures of route learning and landmark recall. These results suggest that the patterns of route learning that have been ascribed to women and men are present in girls and boys.     

Why You Can't Kick the Bucket as You Slowly Die: Verbs in Idiom Comprehension

Idiomatic phrases differ in their degree of analyzability. Some idioms are highly decomposable with their parts independently contributing to their overall figurative meaning (e.g. pop the question) while other idioms are nondecomposable with parts that do not contribute to their idiomatic meaning (e.g. kick the bucket). Nonetheless, even the parts of nondecomposable idioms might have a role in determining what they specifically mean. For example, the verb kick, in kick the bucket implies a quickness or suddenness to the death such that kick the bucket means to die suddenly rather than to die slowly. We report the findings of three experiments showing, in different ways, how the action of the verb contributes to the overall figurative meaning for some nondecomposable idioms. Together, these studies suggest that even nondecomposable idioms are not truly frozen as, at least, part of their overall figurative meanings are shaped by the particular verbs used in these phrases.     

The reviewing of object files: object-specific integration of information.

A series of experiments explored a form of object-specific priming. In all experiments a preview field containing two or more letters is followed by a target letter that is to be named. The displays are designed to produce a perceptual interpretation of the target as a new state of an object that previously contained one of the primes. The link is produced in different experiments by a shared location, by a shared relative position in a moving pattern, or by successive appearance in the same moving frame. An object-specific advantage is consistently observed: naming is facilitated by a preview of the target, if (and in some cases only if) the two appearances are linked to the same object. The amount and the object specificity of the preview benefit are not affected by extending the preview duration to 1 s, or by extending the temporal gap between fields to 590 ms. The results are interpreted in terms of a reviewing process, which is triggered by the appearance of the target and retrieves just one of the previewed items. In the absence of an object link, the reviewing item is selected at random. We develop the concept of an object file as a temporary episodic representation, within which successive states of an object are linked and integrated.     

Conditioning of the rabbit's nictitating membrane response to a CSA-CSB-US serial compound: manipulations of CSB's associative character.

Response acquisition to a trace conditioned stimulus (CSA) can be facilitated by insertion of a second stimulus (CSB) at the end of the trace interval just before the unconditioned stimulus (US). This effect may arise from serial mediation of trace conditioning, second-order conditioning, or both. Whereas serial mediation relies only on the presence of CSB, associative transfer relies on CSB's associative strength. In the present experiments, the presence of CSB was fixed, whereas CSB's associative strength was manipulated by (a) extinction of CSB, (b) latent inhibition of CSB, and (c) prior CSB-US pairings. In the first 2 cases, the level of responding to CSA was reduced in a fashion parallel to that of CSB. However, in the third case, partial blocking of conditioned response (CR) acquisition to CSA was observed. The results are discussed with reference to the role of associative transfer to both facilitating and blocking CR acquisition to CSA.
