Which route to recovery? Controlled retrieval and accessibility bias in retroactive interference

New learning often interferes with the production of older, previously learned responses. However, the original responses usually appear to spontaneously recover and regain their dominance after a delay. This article takes a new approach to questions of interference and recovery by examining performance on immediate and delayed tests using direct or indirect instructions. Direct instructions asked participants to deliberately retrieve the original responses, and indirect instructions allowed them to respond on a more automatic basis, using whatever response came to mind first. Results suggest that interference and recovery may have their largest effects via relatively automatic influences on memory, such as the accessibility of new versus original information. This finding adds a new perspective to classic theories of interference and recovery, and may also inform current understanding of performance in populations (e.g., older adults) that often rely predominantly on automatic memory processing.     

Does face familiarity influence speechreadability?

The impact of face familiarity on the speechreadability of faces is examined. First we measured the baseline speechreading performance of participants, from unfamiliar faces. Next, participants were familiarized with the face and voice of either the same or a different speaker, or were asked to take part in a word puzzle instead. Speechreading performance was measured again, before participants completed a further period of familiarization (or puzzle completion) and a final speechreading performance task. Results showed that speechreading performance increased overall with practice but that performance increased significantly more as participants became increasingly familiar with the same speaker. Our findings demonstrate the importance of talker-specific variations or other instance-based characteristics and suggest that these are a useful source of information for speechreading.     

How can psychotherapists influence psychiatry?

Summary

This paper is based on an invited contribution to the first APP conference on psychoanalytic psychotherapy services in Europe. I was asked to address the question “How can psychotherapists influence psychiatry?” within the overall title for the half-day session of “Psychiatry and Psychodynamics: Towards integration or splitting”. As a background to later discussion I began with a historical sketch of how we had arrived at the current situation in the UK with a specialty of psychotherapy, both separate from and yet still within psychiatry. I argued the need for a separate specialty to protect the space needed for psychotherapy in the face of the inevitable polarisations that occur within psychiatry. Some of the tensions between the different points of view are likened to those between masculine and feminine roles. This specialty might eventually emerge into or foster a new profession of psychotherapy but will still need to negotiate its position in relation to psychiatry.     

Does positive affect influence health?

This review highlights consistent patterns in the literature associating positive affect (PA) and physical health. However, it also raises serious conceptual and methodological reservations. Evidence suggests an association of trait PA and lower morbidity and of state and trait PA and decreased symptoms and pain. Trait PA is also associated with increased longevity among older community-dwelling individuals. The literature on PA and surviving serious illness is inconsistent. Experimentally inducing intense bouts of activated state PA triggers short-term rises in physiological arousal and associated (potentially harmful) effects on immune, cardiovascular, and pulmonary function. However, arousing effects of state PA are not generally found in naturalistic ambulatory studies in which bouts of PA are typically less intense and often associated with health protective responses. A theoretical framework to guide further study is proposed.

Why does asking questions change health behaviours? The mediating role of attitude accessibility

Objective: The question-behaviour effect (QBE) refers to the finding that measuring behavioural intentions increases performance of the relevant behaviour. This effect has been used to change health behaviours. The present research asks why the QBE occurs and evaluates one possible mediator – attitude accessibility.

Design: University staff and students (N = 151) were randomly assigned to an intention measurement condition where they reported their intentions to eat healthy foods, or to one of two control conditions.

Main outcome measures: Participants completed a response latency measure of attitude accessibility, before healthy eating behaviour was assessed unobtrusively using an objective measure of snacking.

Results: Intention measurement participants exhibited more accessible attitudes towards healthy foods, and were more likely to choose a healthy snack, relative to control participants. Furthermore, attitude accessibility mediated the relationship between intention measurement and behaviour.

Conclusion: This research demonstrates that increased attitude accessibility may explain the QBE, extending the findings of previous research to the domain of health behaviour.     

Studies in social influence VI: Is Lenin orange or red? Imagery and social influence

Two experiments dealing with the effects of a majority or a minority source influence, solely on the recognition of a portrait, let us study the generalization of the influence to a portrait symbolically linked to a colour. According to the theory of conversion, the bringing into play of the validation process of the stimulus when the source is a minority should allow such a generalization cognitive association. When the source is a majority, a social comparison process should lead to compliance about the portrait, without any cognitive investigation of the whole stimulus. In the first experiment, four slides were shown successively using material similar to Luchins' (1945) and progressively drawing the portrait of Lenin, with a red-orange background for each phase. The dependant variables are: (1) the drawing, (2) the colour of the background, (3) the after-image. On the two last slides for which the answer ‘Lenin’ is given by the source, changes towards red (and the complementary colour green), in the absence of the source under the minority influence, and changes towards orange under majority influence in the absence of the source are registered. Moreoever, the most significant changes of the colour judgment are due to the subjects who refuse to answer ‘Lenin’ during the interaction. In the second experiment, only the fourth slide, on which Lenin's portrait completely appears is shown. The subjects submitted to majority influence answer ‘Lenin’ more than the control group does, only in the presence of the source and change their judgment on the colour of the after-image towards the complementary of orange in the absence of the source. When the source is a minority a sinificant effect towards the red and its complementary colour is shown.     

Affect, accessibility of material in memory, and behavior: a cognitive loop?

Two studies investigated the effect of good mood on cognitive processes. In the first study, conducted in a shopping mall, a positive feeling state was induced by giving subjects a free gift, and good mood, thus induced, was found to improve subjects' evaluations of the performance and service records of products they owned. In the second study, in which affect was induced by having subjects win or lose a computer game in a laboratory setting, subjects who had won the game were found to be better able to recall positive material in memory. The results of the two studies are discussed in terms of the effect that feelings have on accessibility of cognitions. In addition, the nature of affect and the relationship between good mood and behavior (such as helping) are discussed in terms of this proposed cognitive process.     

Does prime modality influence morphological processing?

Facilitation among morphologically related words generally is impervious to the prefixed or suffixed structure of primes and targets. A notable exception arises, however, when both primes and targets are suffixed. More specifically, when primes are auditory and targets are visual, facilitation for a suffixed target (e.g., payment) is absent when it follows a prime (e.g., payable) that is morphologically related and suffixed (Marslen-Wilson, Tyler, Waksler, & Older, 1994). To account for null facilitation (viz., the "suffix-suffix" effect), Marslen-Wilson and his colleagues posit inhibitory links between suffixes of morphological relatives. The present study assesses the generality of the "suffix-suffix" effect. When morphological facilitation is assessed relative to an orthographically related baseline, suffixed primes facilitate derivationally as well as inflectionally related morphological targets when primes are visual as well as auditory in both the lexical decision and naming tasks. The present findings call into question lexical models that posit inhibitory links between suffixes of morphological relatives.     

Can semantic knowledge influence motion correspondence?

Semantic factors are presumed to have little influence on motion perception. Two experiments examined the effects of an object's semantic identity on motion correspondence using the Ternus paradigm. Motion correspondence was not influenced by whether the object depicted is typically moving or stationary, but it was influenced by the way(s) in which an object's components typically move relative to one another: perceived correspondence differed depending on whether the motion tokens constituted the feet of a person walking or the wheels of a car. Apparently, semantic knowledge can influence motion correspondence, although such influence is weak and may be restricted to certain types of semantic information. The adaptive significance of such restricted influences is considered.     

Can research influence clinical practice?1

After briefly reviewing the unfavourable reception accorded empirical research by parts of the psychoanalytic community, as well as some of the benefits to clinical practice of analysts being involved in research activities, the author examines whether the findings of process and outcome research in psychotherapy and psychoanalysis can help identify the most appropriate forms of intervention for producing therapeutic change, given the specific condition of the patient and the relationship that the individual establishes with the analyst. He argues that research findings can influence clinical practice on various levels and in different areas, and goes on to examine a number of related issues: the specificity of therapeutic interventions versus the relevance of common curative factors; the dyadic conception of technique and ways of understanding the therapeutic action of the treatment alliance; and the strategic or heuristic conception in psychoanalytic therapy. Finally, the author presents clinical material with the aim of illustrating how the knowledge acquired through research can be applied to psychoanalytic treatment.     

Do traumatic events influence cognitive schemata?

Within the field of crisis psychology empirical research on the subject whether cognitive schemata are influenced by victimization, and whether possible changes in cognitive schemata are related to post-traumatic stress disorder (PTSD) is somewhat sparse. In the present study cognitive processing of 602 parents, who had lost an infant, were examined. Among other things results showed a significant relationship between level of cognitive processing and symptoms of PTSD. When items selected to reflect fundamental assumptions about the self and the world were assessed, there were only few differences between parents who had lost an infant, and the control group. Furthermore, there were numerous significant relations between items selected to reflect fundamental assumptions and symptoms of PTSD. The results are discussed in relation to central theories within the cognitive area of crisis psychology and recommendations for future research are offered.     

Do reference surfaces influence exocentric pointing?

All elements of the visual field are known to influence the perception of the egocentric distances of objects. Not only the ground surface of a scene, but also the surface at the back or other objects in the scene can affect an observer's egocentric distance estimation of an object. We tested whether this is also true for exocentric direction estimations. We used an exocentric pointing task to test whether the presence of poster-boards in the visual scene would influence the perception of the exocentric direction between two test-objects. In this task the observer has to direct a pointer, with a remote control, to a target. We placed the poster-boards at various positions in the visual field to test whether these boards would affect the settings of the observer. We found that they only affected the settings when they directly served as a reference for orienting the pointer to the target.     

Does code-switching influence novel word learning?

Code-switching occurs regularly in the input to bilingual children. Yet, the effect of code-switched input on language development is unclear. To test whether word learning would be affected by code-switching, Spanish–English bilingual children (N = 45, 19 boys, Mean_Age = 5.05 years; ethnicity: 37 Hispanic/Latino, six Non-Hispanic/Latino, two unreported) were taught English-like novel words in two conditions. In the English-only condition, definitions for novel words were provided entirely in English. In the code-switch condition, definitions for novel words were provided in English and Spanish, incorporating code-switches. Children required fewer exposures to retain novel words in the code-switch than the English-only condition and this effect was not moderated by children's language ability or exposure to code-switching, suggesting that code-switched input does not pose word-learning risks to bilingual children, including children with lower levels of language ability.     

Does service failure influence customer loyalty?

There is a general consensus that customer loyalty to service providers is not solely dependent upon their level of satisfaction or dissatisfaction. However, the identified antecedents of loyalty remain, at best, highly speculative. The aim of this extensive literature review is to give some understanding of the nature of customer loyalty and the antecedent effects of service dissatisfaction. The research reviewed suggests that customer loyalty is an attitudinal state, reflecting value, trust and commitment within supplier–customer relationships. Satisfaction is one of several antecedents of loyalty. A key influence on loyalty is the offer of unique value‐delivering advantages not provided by competitors. Thus firms need to develop positive value‐based exit barriers to achieve loyalty. When service failures occur, the recovery process is likely to have a greater impact on loyalty than the original service failure. The key to successful recoveries was found to be the customer's perception of ‘fairness’. Recovery programmes must get it right first time. Customers who remain dissatisfied after a complaint has been handled are more dissatisfied than if no recovery attempt had been made. Dissatisfaction and customer satiation are major causes of a customer's exit. The solution to customer satiation is dynamic value creation. Collection and monitoring of customer data is needed for success and two‐way communication is vital. Copyright © 2002 Henry Stewart Publications.     

What remains on your mind after you are done?: Flexible regulation of knowledge accessibility

The accessibility of stored knowledge has been found to decline over time after activation without further stimulation. A special case is goal pursuit; goal-related knowledge remains accessible until goal completion, and then its accessibility declines rapidly. We hypothesized that after goal completion the decline in accessibility of goal-related knowledge would be especially rapid for strong promotion-focused individuals because their motivation to eagerly advance beyond the status quo would make accessibility of this knowledge an irrelevant detriment. We hypothesized an opposite effect for strongly prevention-predominant individuals because their motivation to vigilantly maintain a satisfactory state would make accessibility of this knowledge continually relevant. The results of two studies supported both these predicted moderators of accessibility change. Indeed, we found that for strongly prevention-predominant participants, knowledge accessibility actually increased over time after goal completion. We discuss how even basic cognitive mechanisms, like changes in accessibility, can be affected by general motivational concerns.
