Development and crossmodal transfer of contextual control of emergent stimulus relations

Six normally capable adults first learned three conditional relations in each of two prospective equivalence classes via match-to-sample training with figures as conditional (sample) and discriminative (comparison) stimuli. Then one trained conditional relation in each prospective class was brought under the control of contextual stimuli, two dictated nonsense syllables. Test performances indicated the emergence of untrained conditional relations, and therefore two equivalence classes, that were conditional on the contextual stimuli. These tests involved untrained combinations of contextual stimuli and stimuli in conditional relations, suggesting that the contextual stimuli functioned independently to control conditional relations rather than forming compound stimuli with samples and comparisons in training. Next, two novel figures were made equivalent to each of the original dictated contextual stimuli by match-to-sample training and testing. On subsequent tests, all subjects demonstrated transfer of conditional control of untrained conditional relations from the original auditory contextual stimuli to equivalent visual stimuli. These outcomes further supported the conclusion that the contextual stimuli exerted true conditional control over conditional relations in the equivalence classes and were not merely elements of compound stimuli.     

Brightness contrast: a reinterpretation of compound cue and combined cue experiments with pigeons.

A group of three pigeons was trained on a 4-ply multiple schedule: a green color and a vertical line superimposed upon an achromatic background as positive stimuli, and a red color and a horizontal line on an achromatic background as negative stimuli. The pigeons were tested with the vertical line superimposed upon different achromatic background intensities, then with the vertical line superimposed upon different green background intensities, and finally with the vertical line and its training achromatic backgfound attenuated (and unattenuated) by a neutral density filter. The gradients peaked at the luminance of the achromatic background used during training and at the equivalent luminance for the green background when it was substituted for the achromatic background. The brightness contrast, not the background luminance, was the critical variable as the neutral density filter attenuated both the line and the background equally, leaving brightness contrast unchanged; there was no response decrement to this attenuated stimulus. Two other groups of three pigeons showed that they attended to line orientation as well as to brightness contrast. The brightness contrast hypothesis was extended to explain results of attention experiments and combined cue experiments which have used line stimuli in combinations with different backgrounds.     

The art of the tincture: analytical supervision

Using the alchemical metaphor, effective supervision can be seen as an excellent example of the tincture: a little goes a long way. This paper offers a model of the dynamics in analytical supervision: a mirroring of the professional-self of the supervisee, the opportunity to learn through empirical factual knowledge, and, most importantly, experiential, interactive and dynamic learning. The container of supervision will be amplified using an image of the triple vessel of alchemy. The materia of supervision is discussed as 'amalgams' of complex related material. The supervisory field is seen in a triadic intersubjective and interimaginal manner. Jung's diagram of all the possible conscious and unconscious connections between patient and therapist is expanded to include the supervisory situation. Moving beyond projective identification as explanatory process, the concept of the mundus imaginalis is used as the medium for this triadic structure. The 'analytic third' expands to include the 'supervisory fourth' while incorporating the supervisor's imaginings of the patient as the quintessential experience of the imaginal other. The supervisor's attitude and state of mind are seen through the paradigm of active imagination. This state of mind is called supervisory reverie.     

Psychological science in the public arena: Three cases of dubious influence

Psychological science has a great deal to contribute to social welfare in all societies, because the world's most pressing social problems are behavioral in nature—violence, hunger, drug abuse, environmental pollution, low worker productivity, poor educational outcomes, and so forth. Thus, psychological research can inform public policies to improve approaches to these important social problems. The relationship of psychological science to public policy is often troubled, however, by misunderstandings about the role of science in the policy making process. Many scientists fear that their research results will be "misused" by others whose values differ from those of scientists. Thus, psychologists are reluctant to publish research results that can be used to support policies contrary to their own values and hesitate to ask research questions that can generate politically incorrect results. In this article, I argue that psychological science has a primary responsibility to ask dangerous questions and to report results honestly, without fear of their use; that research is not translated directly into public policies; and that psychological science should not be perverted either by fear of political consequences or by compromising truth in a quest for power. Three research examples are given to illustrate the different faces of temptation to pervert psychological science in a misguided hope that scientists' own values will be reflected in public policies.     

Serial conditioning as a function of stimulus, response, and temporal dependencies

Six experiments were used to examine the effects of explicit response, stimulus, and temporal dependencies on responding in an interfood interval. The first two experiments demonstrated that 10-segment 60-s interfood clocks controlled similar distributions of key pecking in pigeons regardless of whether response–reinforcement contiguity was required, allowed, or precluded. The third and fourth experiments found that in the absence of an explicit response–reinforcement dependency, systematic explicit stimuli in an interfood interval were sufficient to establish and maintain the characteristic distribution of key pecking and that an interval without an explicit clock failed to establish or maintain key pecking. The last two experiments demonstrated that the interfood interval need not be of fixed length, and that a simple correlation of stimuli with increments from either a minimum to a maximum imminency or probability of food presentation controlled behavior in a similar manner. Successively higher rates generally occurred to successively later stimuli in the upper half of the range.     

Psychometric Evaluation of an Alternate Scoring for the Remote Associates Test

The Remote Associates Test (RAT; Mednick, 1962; Mednick & Mednick, 1967) is a commonly employed test of creative convergent thinking. The RAT is scored with a dichotomous scoring, scoring correct answers as 1 and all other answers as 0. Based on recent research into the information processing underlying RAT performance, we argued that the dichotomous scoring may lead to a loss of potentially relevant information. Thus, we proposed an alternate scoring based on semantic similarity between the answer given by the participant and the correct solution using Latent Semantic Analysis (LSA; Landauer & Dumais, 1997). We evaluate the psychometric properties of the alternate LSA scoring and found evidence of construct validity for the LSA scoring which was comparable to findings for the standard scoring, but not better as we would have expected. Thus, our expectations that LSA-based scoring of the RAT counteracts potential information loss were not met. However, LSA based scorings appear to be a promising alternative for hardly solvable RAT items. We conducted additional analyses comparing different RAT item types with regard to their validity as well as evaluating the information uniquely contained in the LSA scoring. Implications of all finding for existing research using RAT items are discussed.

Reciprocal relationships between State gratitude and high- and low-arousal positive affects in daily life: A time-lagged ecological assessment study

ABSTRACT

This study assessed whether state gratitude and high and low-arousal positive affect show reciprocal relationships in daily life, and whether these relationships are dependent of inter-individual differences in positive mental health or psychopathology. 106 participants reported on momentary gratitude and positive affects throughout 7 consecutive days, using the Experience Sampling Method. Multilevel time-lagged regression analyses showed that state gratitude, cheerfulness and satisfaction reciprocally predict one another from one moment to the next. The strength of the prospective relationships between state gratitude(t-1) and both cheerfulness(t) and satisfaction(t) did not vary as a function of inter-individual differences in positive mental health or psychopathology. However, the prospective effects of both cheerfulness(t-1) and satisfaction(t-1) on state gratitude(t) were significantly stronger for individuals with low vs. high levels of psychopathology. In addition, the prospective effect of cheerfulness(t-1) on state gratitude(t) was significantly stronger for those with high vs. low positive mental health.     

A Puzzle Regarding Reid's Theory of Motives

In Essays on the Active Powers, Thomas Reid offers two different accounts of motives. According to the first, motives are the ends for which we act. According to the second, they are mental states, such as desires, that incite us to action. These two accounts, I claim, do not fit comfortably with Reid's agent causal account of human action. My project in this article is to explain why and then to propose a strategy for reconciling these two accounts with Reid's views about action.
