Self-discrimination and memory : state orientation and false self-ascription of assigned activities

A new paradigm to investigate the tendency to falsely ascribe to oneself assigned goals (misinformed introjection or self-infiltration) and the better memory of self-chosen than of assigned prospective activities (self-choice effect) is explored. In two experiments, state-oriented subjects showed significantly higher rates of false self-ascriptions of assigned activities than action-oriented subjects did (an individual-difference factor related to volitional efficiency; Kuhl & Beckmann, 1994b), whereas all subjects gave evidence of the self-choice effect. Specific manipulations to reduce and to increase the probability of occurrence of false self-ascriptions were also carried out (an intentional-learning instruction and task interruption, respectively). Finally, a first step was taken to examine the relationship between self-infiltration and the tendency to enact more self-chosen than assigned activities (self-determination).

When Nonsense Sounds Happy or Helpless: The Implicit Positive and Negative Affect Test (IPANAT)

This article introduces an instrument for the indirect assessment of positive and negative affect, the Implicit Positive and Negative Affect Test (IPANAT). This test draws on participant ratings of the extent to which artificial words subjectively convey various emotions. Factor analyses of these ratings yielded two independent factors that can be interpreted as implicit positive and negative affect. The corresponding scales show adequate internal consistency, test-retest reliability, stability (Study 1), and construct validity (Study 2). Studies 3 and 4 demonstrate that the IPANAT also measures state variance. Finally, Study 5 provides criterion-based validity by demonstrating that correlations between implicit affect and explicit affect are higher under conditions of spontaneous responding than under conditions of reflective responding to explicit affect scales. The present findings suggest that the IPANAT is a reliable and valid measure with a straightforward application procedure.

Imagery mnemonics for the rehabilitation of memory: A randomised group controlled trial

Apart from a few, encouraging, single-case studies, evidence of imagery-based mnemonics for the rehabilitation of memory in brain-damaged individuals is sparse. The literature suggests that if imagery is of any use, then it should be applied to mildly memory impaired patients, the learning process should be tailored and a direct transfer training to individual memory problems should be implemented into the training. We compared the outcome of such a programme (nine memory impaired patients) with other approaches to the rehabilitation of memory used in participating centres (12 memory impaired patients). After 4 weeks of baseline and a repeated test battery patients received 30 single sessions of therapy in 10 weeks. Results suggest that imagery training significantly improves delayed recall of everyday relevant verbal materials (stories, appointments). Frequency of memory problems observed by relatives is reduced and each of these effects is stable at 3-month follow-up. This study suggests that a simple imagery technique can improve relevant aspects of everyday verbal memory performance.

Intention memory and achievement motivation: volitional facilitation and inhibition as a function of affective contents of need-related stimuli.

Replicating findings of J. Kuhl and M. Kazén (1999), reduction or removal of Stroop interference was achieved after short exposure to primes eliciting positive affect. This effect was need specific: Stroop interference removal (volitional facilitation) was found with positive primes related to achievement needs but not with positive primes related to affiliation or power needs. Five studies are reported. College students and unemployed university graduates participated in 2 studies each and branch managers of a large insurance company in 1 study. Whereas Stroop interference reduction or removal was found in all groups after positive-achievement primes, the 2 groups of unemployed persons additionally showed a significant increase of Stroop interference (volitional inhibition) after exposure to primes related to negative achievement episodes. Results are discussed in the context of Kuhls personality systems interactions theory.

Self-Infiltration vs. Self-Compatibility Checking in Dealing with Unattractive Tasks: The Moderating Influence of State vs. Action Orientation

Self-infiltration, or false self-ascription of external goals or ideas, is investigated using an implicit experimental procedure (J. Kuhl & M. Kazén, 1994). Based on personality systems interactions (PSI) theory (J. Kuhl, 2000), it was expected that state-oriented participants exposed to task-alienating conditions, under external pressure, or experiencing negative mood would show self-infiltration, because under those conditions access to their self-system is impaired, including integrated representations of personal preferences. A new prediction is that self-infiltration should occur in processing low-attractive goals or ideas and not in processing high-attractive ones, because the latter are internalized through integration or identification with the self. Three experiments yielded results consistent with this hypothesis: State-oriented participants showed self-infiltration with low-attractive items, whereas action-oriented did not show this pattern. A mechanism is proposed that helps people to resist external influences in the formation of personal goals and ideas: Self-compatibility checking. This mechanism is inferred on the basis of long latencies in counter-preferential decisions related to previous self-choices (autonoetic access). Only action-oriented participants gave systematic evidence of autonoetic access.

Implicit but Not Explicit Affectivity Predicts Circadian and Reactive Cortisol: Using the Implicit Positive and Negative Affect Test

Self-report measures assess mental processes or representations that are consciously accessible. In contrast, implicit measures assess automatic processes that often operate outside awareness. Whereas self-report measures have often failed to show expected relationships with endocrine stress responses, little effort has been made to relate implicit measures to endocrine processes. The present work examines whether implicit affectivity as assessed by the Implicit Positive and Negative Affect Test (IPANAT) predicts cortisol regulation. In Study 1, implicit low positive affectivity, but not negative affectivity, significantly predicted circadian cortisol release. In Study 2, implicit negative affectivity, but not positive affectivity, significantly predicted the cortisol response to acute stress. By contrast, cortisol regulation was not predicted by self-reported affectivity. The findings support the use of implicit affectivity measures in studying individual differences in endocrine stress responses and point to a differential role of positive and negative affectivity in baseline versus stress-contingent cortisol release, respectively.

Motivation, affect, and hemispheric asymmetry: Power versus affiliation.

In 4 experiments, the authors examined to what extent information related to different social needs (i.e., power vs. affiliation) is associated with hemispheric laterality. Response latencies to a lateralized dot-probe task following lateralized pictures or verbal labels that were associated with positive or negative episodes related to power, affiliation, or achievement revealed clear-cut laterality effects. These effects were a function of need content rather than of valence: Power-related stimuli were associated with right visual field (left hemisphere) superiority, whereas affiliation-related stimuli were associated with left visual field (right hemisphere) superiority. Additional results demonstrated that in contrast to power, affiliation primes were associated with better discrimination between coherent word triads (e.g., goat, pass, and green, all related to mountain) and noncoherent triads, a remote associate task known to activate areas of the right hemisphere.

Alzheimer’s disease, but not ageing or depression, affects dual-tasking

Two experiments are reported that assess dual task performance in Alzheimer’s disease (AD), in chronic depression and in healthy old age. Results suggest that dual task impairments are present in AD but are not shown in depression. This is true even when episodic memory performance is equated between the groups. These results, together with those of previous studies, point to dual task performance as an aid to diagnosis of AD relative to depression. This is of particular relevance when episodic memory tests cannot distinguish between the two conditions. The dual task paradigm appears to have considerable promise in assisting the early detection of the specific cognitive deficits associated with AD, and in monitoring their progression, both in the laboratory setting and in everyday tasks. Results also are of theoretical interest in pointing to a specific dual task coordination function in the healthy human cognitive system that allows for the coordination of two tasks performed simultaneously and which is damaged in AD but not in depression.

Recognition hypermnesia with repeated trials: Initial evidence for the alternative retrieval pathways hypothesis

The alternative retrieval pathways (ARP) hypothesis of hypermnesia is here proposed. This hypothesis predicts hypermnesia (net improvements in recall or recognition after initial learning) whenever alternative retrieval pathways are provided leading to the original episodic trace. Initial evidence for this hypothesis was obtained in two experiments testing a non-obvious prediction of its format transformation assumption, namely that hypermnesia would be obtained in recognition and would not occur in recall if the former, but not the latter, condition requires obligatory format transformations between item encoding and retrieval. In the first experiment the same participants, exposed to identical items and having analogous encoding and retrieval conditions, showed recognition and did not show recall hypermnesia. With a between-participant design, the second experiment replicated the recognition hypermnesia findings, using a different recognition procedure and three instead of two test trials, whereas recall hypermnesia remained absent. Results are discussed comparing the heuristic value of ARP hypothesis to that of other current theories. It is concluded that recognition hypermnesia using individual words and pictures is a reliable phenomenon, provided ceiling effects can be prevented, and access to the original episodic information takes place using alternative retrieval pathways.

A Cross-Cultural Validation of the Implicit Positive and Negative Affect Test (IPANAT)

Self-report measures of affect come with a number of difficulties that can be circumvented by using indirect measurement procedures. The Implicit Positive and Negative Affect Test (IPANAT) is a recently developed measure of automatic activation of representations of affective states and traits that draws on participants’ ratings of the extent to which nonsense words purportedly originating from an artificial language bear positive or negative meaning. Here we compared psychometric properties of this procedure across 10 countries and provide versions in corresponding languages (Chinese, Dutch, English, French, German, Italian, Polish, Russian, and Spanish). The results suggest good reliability, metric invariance, and construct validity across countries and languages. The IPANAT thus turns out as a useful tool for the indirect assessment of affect in different languages and cultures.
