Mood-congruent free recall bias in anxious individuals is not a consequence of response bias

The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals. This group was significantly slower in naming the colour in which threat-related words were displayed compared to neutral words. In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people. This difference was significant even when controlling for the false recall of items that had not been presented during study. These results support the view put forward by Russo, Fox, Bellinger, and Nguyen-Van-Tam (2001) that mood-congruent free recall bias in anxious individuals can be observed if the target material is encoded at a relatively shallow level. Moreover, contrary to Dowens and Calvo (2003), the current results show that the memory advantage for threat-related information in anxious individuals is not a consequence of response bias.     

Toward a unified account of spacing effects in explicit cued-memory tasks

Memory for repeated items improves when presentations are spaced during study. This effect is found in memory tasks using different types of material, paradigms, and participant populations. Although several explanations have been proposed, none explains the presence of spacing effects in cued-memory tasks for unfamiliar stimuli. Two experiments assessed the spacing effect on a yes-no recognition-memory task using nonwords and words as targets. The main results showed that changing the font between repeated occurrences of targets at study removed the spacing effect for nonwords only. A 3rd experiment using lexical decision showed that the font manipulation reduced repetition priming of nonwords when items were repeated at Lag 0. These results suggest that short-term perceptual priming supports spacing effects in cued-memory tasks for unfamiliar stimuli.     

Age differences and the identity negative priming effect: an updated meta-analysis

A recent meta-analysis (P. Verhaeghen & L. De Meersman, 1998a) revealed that older adults show a reliable but significantly reduced negative priming effect compared with young adults. The present study provides an updated quantitative review on the effect of aging on the magnitude of the negative priming effect in identity tasks. This analysis demonstrated that the negative priming effect was not significantly different between young and old adults. This result differs from P. Verhaeghen and L. De Meersman's study. The implications of this finding for inhibitory-based theories of cognitive aging are discussed.     

To master or perform? Exploring relations between achievement goals and conceptual change learning

Background. Research is needed to explore conceptual change in relation to achievement goal orientations and depth of processing. Aims. To address this need, we examined relations between achievement goals, use of deep versus shallow processing strategies, and conceptual change learning using a think‐aloud protocol. Sample and Method. Seventy‐three undergraduate students were assessed on their prior knowledge and misconceptions about Newtonian mechanics, and then reported their achievement goals and participated in think‐aloud protocols while reading Newtonian physics texts. Results. A mastery‐approach goal orientation positively predicted deep processing strategies, shallow processing strategies, and conceptual change. In contrast, a performance‐approach goal orientation did not predict either of the processing strategies, but negatively predicted conceptual change. A performance‐avoidance goal orientation negatively predicted deep processing strategies and conceptual change. Moreover, deep and shallow processing strategies positively predicted conceptual change as well as recall. Finally, both deep and shallow processing strategies mediated relations between mastery‐approach goals and conceptual change. Conclusions. Results provide some support for Dole and Sinatra's (1998) Cognitive Reconstruction of Knowledge Model of conceptual change but also challenge specific facets with regard to the role of depth of processing in conceptual change.     

Simultaneous completions of modal and amodal figures: Visual evoked potentials reveal asymmetrical interference effects

Modal and amodal completion processes are thought to affect the emergence and the potency of each other. To see whether one dominates over the other, we measured the Npd, that is, the negativity of visual-evoked potentials whose amplitude increases with perceptual difficulty. In the first experiment, the Npds to illusory (modal) squares and diamonds placed over amodal diamonds and squares, respectively, were found to be greater when targets were the amodal figures than when targets were the modal figures, thus suggesting that modal figures created more interference. A second experiment showed that greater Npds were specific to interference and not to the greater difficulty at focusing on amodal figures rather than on modal figures. A third experiment showed that the interference also occurs with real figures in replacement of modal ones. Overall, the results suggest a certain dominance of modal completion over amodal completion when both occur in the same display.     

On the Patient's Becoming an Individual: The Importance of the Analyst's Personal Response to a Deprived Patient and Her Dreams

What patients mainly want—which Ferenczi noted as early as 1932 in his clinical diary and which Bion later expressed in his Cogitations (1992)—and what some patients need, is to experience how the analyst lives and processes the interpersonal events that lie at the origin of their affective and mental suffering. This is especially true with schizoid patients who were profoundly emotionally deprived in childhood. In this paper, the author investigates this crucial aspect of the intersubjective analytic relationship in his treatment of just such a patient, an extremely silent and inert young woman. Through a detailed examination of clinical material from various stages of her analysis, he explores how the analyst's unconscious emotional response serves as both a tool for comprehension and a key element of environmental facilitation—a “new beginning,” to use Balint's phrase—that may help the patient attain a level of development and emancipation that he or she has never experienced before.     

Flexibility of the Psychoanalytic Approach in the Treatment of a Suicidal Patient: Stubborn Silences as “Playing Dead”

The author presents the clinical case of a patient in his third analysis who seemed emotionless, did not feel alive, and complained of an uncontrollable urge to gamble, with disastrous financial results. His previous four-session-a-week “orthodox” analysis had left him prey to a sense of emptiness and to intense suicidal urges. He wanted only two weekly sessions, which became three after some analytic work. The author stresses the danger of rigidly following inflexible standards and the consequent activation of a pseudo-compliance in the analysand. A more slowly paced psychoanalysis should not be considered lower in the pecking order than “high-frequency” treatment, the author maintains: It requires great creative subjective involvement on the part of the analyst and close interaction in the context of the analytic couple. The author shows how this analysis involved a series of interactions in which the analyst was called upon to exercise a complex responsiveness, attuned in each instance to the patient's current needs. Finally he focuses on some clinical passages to show how the patient's internal theories represent a glaring assault on common sense and how death was not recognized perceptionally on a realistic level, but was instead replaced with acting out death against himself by keeping himself mentally dead and by suicidal urges.     

Response-dependent point loss and response force as disrupting operations on behavioral resistance to change in humans

Behavioral momentum theory (BMT) provides a theoretical and methodological framework for understanding how differentially maintained operant responding resists disruption. A common way to test operant resistance involves contingencies with suppressive effects, such as extinction or prefeeding. Other contingencies with known suppressive effects, such as response-cost procedures arranged as point-loss or increases in response force, remain untested as disruptive events within the BMT framework. In the present set of three experiments, responding of humans was maintained by point accumulation programmed according to a multiple variable-interval (VI) VI schedule with different reinforcement rates in either of two components. Subsequently, subtracting a point following each response (Experiment 1) or increasing the force required for the response to be registered (Experiments 2 and 3 decreased response rates, but responding was less disrupted in the component associated with the higher reinforcement rate. The point-loss contingency and increased response force similarly affected response rates by suppressing responding and human persistence, replicating previous findings with humans and nonhuman animals when other types of disruptive events (e.g., extinction and prefeeding) were investigated. The present findings moreover extend the generality of the effects of reinforcement rate on persistence, and thus BMT, extending the analysis of resistance to two well-known manipulations used to reduce responding in the experimental analysis of behavior.
