The consequence of refreshing for access to nonselected items in young and older adults

We examined the effect of competition on briefly thinking of just-seen items. In Experiment 1, participants saw a set of either three related or three unrelated words and then read one of the words again (repeat) or thought briefly of one of the words (refresh). Participants read the set a second time, after which they either refreshed a second word from the set or read a new word. In comparison with reading a new word, response times were slower for refreshing the second item when participants had just refreshed than when they had just repeated the first item. This increase was larger for related words than for unrelated words and for older adults than for younger adults. In Experiment 2, a negative impact of refreshing was observed when participants repeated a different word from the set. The pattern of findings suggests that the negative impact of refreshing comes from increased competition from the refreshed item, rather than from inhibition of the nonrefreshed items.     

The effects of diazepam and triazolam on repeated acquisition and performance of response sequences with an observing response.

Drugs often disrupt the acquisition of new response sequences at doses that fail to disrupt the performance of a previously acquired response sequence. This selective drug effect may result from differences in the control exerted by the stimuli presented after each response in the acquisition and performance sequences. To examine the function of these stimuli, an observing procedure was incorporated into a multiple schedule of repeated acquisition and performance of response sequences, in which stimulus presentations were contingent upon an observing response. Three experiments were conducted with humans. Experiment 1 compared responding with and without the observing contingency. No difference was found in the overall percentage of errors across the two conditions. Within the observing condition, observing behaviour was maintained in the acquisition component as long as errors occurred, but was not maintained in the performance component. Experiment 2 examined whether a contingency that increased errors also would increase observing in both the acquisition and performance components. Specifically, reinforcer delivery in each component was contingent upon emitting 10 correct responses and one, two, or four errors. Observing responses increased in the acquisition component as the error requirement increased, whereas observing responses in the performance component increased only when the error requirement was four. Experiment 3 assessed the effects of diazepam (0, 7.5, 15, and 30 mg/70 kg, p.o.) and triazolam (0, 0.375, and 0.75 mg/70 kg, p.o.) on repeated acquisition and performance baselines with the observing contingency. Selective drug effects were obtained in this modified procedure; that is, the percentage of errors in the acquisition component increased at doses that failed to affect the percentage of errors in the performance components. Importantly, drug effects were selective, even though observing responses were not emitted in the performance component and, hence, the stimulus presentations did not occur in that component. These findings suggest that alternative explanations for these differential effects are needed; in that regard, a response-unit account of the selective drug effects is discussed.     

Biosocial selfhood: overcoming the ‘body-social problem’ within the individuation of the human self

In a recent paper, Kyselo (2014) argues that an enactive approach to selfhood can overcome ‘the body-social problem’: “the question for philosophy of cognitive science about how bodily and social aspects figure in the individuation of the human individual self” (Kyselo 2014, p. 4; see also Kyselo and Di Paolo (2013)). Kyselo’s claim is that we should conceive of the human self as a socially enacted phenomenon that is bodily mediated. Whilst there is much to be praised about this claim, I will demonstrate in this paper that such a conception of self ultimately leads to a strained interpretation of how bodily and social processes are related. To this end, I will begin the paper by elucidating the body-social problem as it appears in modern cognitive science and then expounding Kyselo’s solution, which relies on a novel interpretation of Jonas’s (1966/2001) concept of needful freedom. In response to this solution, I will highlight two problems which Kyselo’s account cannot overcome in its current state. I will argue that a more satisfactory solution to the body-social problem involves a re-conception of the human body as irrevocably socially constituted and the human social world as irrevocably bodily constituted. On this view, even the most minimal sense of selfhood cannot privilege either bodily or social processes; instead, the two are ontologically entwined such that humans are biosocial selves.     

Managing others like you were managed: how prevention focus motivates copying interpersonal norms

In 5 studies, we investigated the relation between regulatory focus and the tendency to copy a role model's managing behavior after one experiences this behavior as its recipient and later takes on the same managing role. Because enacting role-related behaviors fulfills interpersonal norms that fit prevention concerns, we predicted a stronger tendency to copy among individuals with a stronger prevention focus on duties and obligations ("oughts") but not among those with a stronger promotion focus on aspirations and advancements (ideals). We also predicted that individuals with a stronger prevention focus would tend to copy a managing behavior regardless of their earlier hedonic experience with this behavior as its recipient. These predictions were first supported in 2 experimental studies, where a stronger prevention focus was measured as a chronic disposition (Study 1) and experimentally induced as a temporary state (Study 2). Further, we tested the mechanism underlying the relation between stronger prevention and stronger copying and found that concerns about the normativeness, but not the effectiveness, of a managing behavior motivated copying for individuals with a strong prevention focus (Studies 3 and 4). We generalized these experimental results to the field by surveying a sample of superior-subordinate dyads in real world organizations (Study 5). Across all studies, we found that individuals with a stronger prevention focus tend to copy more a role model's managing behavior--independent of their hedonic satisfaction with the behavior as its recipient and their perception of its effectiveness.     

Memory Errors From A Change of Standard: A Lack of Awareness or of Understanding?

Memory errors occur when the context standard that is used when judging target behaviors is different from the category norm standard that is available later when the behaviors are recalled. Is insufficient awareness the reason for this change-of-standard effect? Two kinds of awareness were maximized in each of two studies: (a) awareness of the relation between the judgment and the context - telling subjects to be sure to use the non-target persons for comparison when judging the target person (salience); and (b) awareness at recall of the earlier judgmental context - asking subjects to recall the non-target persons before recalling the target person (reinstatement). Context reinstatement reduced memory errors. But when context reinstatement and salience were combined, the memory errors reappeared. In Study 2, an attempt at debiasing failed. The change-of-standard effect is explained in terms of a "natural" tendency to use the current categorical meaning of a judgment to reconstruct the referent of its past contextualized meaning.     

Tactical differences in coping with rejection sensitivity: the role of prevention pride

Prevention pride reflects a person's subjective history of success in preventing negative outcomes, leading to a strategic avoidance of errors of commission (e.g., explicit mistakes) in new situations. Two studies examined the impact of prevention pride on the strategies that highly rejection sensitive (HRS) people use to cope with the anxiety of anticipated rejection and the negative feelings elicited by perceived rejection. It was hypothesized that prevention pride orientation would lead HRS people toward covert and passive rather than overt and active forms of negative coping. Results indicated that HRS individuals who were also high in prevention pride reported increased use of self-silencing, presumably to prevent rejection. When rejection was perceived, however, they expressed hostility passively, by reducing positive behavior (e.g., withdrawing love and support) while inhibiting direct, active acts of hostility (e.g., yelling).     

Emergent equivalence relations between interoceptive (drug) and exteroceptive (visual) stimuli.

Conditional "if-then" relations between drug (interoceptive) stimuli and visual (exteroceptive) stimuli were taught to 4 normal humans. Interoceptive stimuli were the effects produced by 0.32 mg/70 kg triazolam (a prototypical benzodiazepine) and placebo (lactose-filled capsules); exteroceptive stimuli were black symbols on white flash cards. Following the training of the prerequisite conditional relations, tests of emergent relations were conducted between exteroceptive stimuli and between interoceptive and exteroceptive stimuli. Equivalence relations emerged immediately without explicit training for all 4 subjects. Accuracy of responding during the interoceptive-exteroceptive equivalence tests and subjects' self-reports showed consistent discrimination between the drug effects of triazolam and placebo. Finally, a generalization test assessed whether a novel visual stimulus presented in the context of the placebo (i.e., no drug) would generalize to visual stimuli belonging to the placebo stimulus class. All 3 subjects who completed this test reliably chose the visual stimuli belonging to the placebo class and not the visual stimuli belonging to the triazolam stimulus class. The development of equivalence relations between interoceptive and exteroceptive stimuli demonstrates that private and public stimulus events can emerge as members of the same equivalence class. Theoretical and clinical implications are discussed.     

Automatic social behavior as motivated preparation to interact

The authors propose that automatic social behavior may result from perceivers preparing to interact with primed social group members. In Study 1, participants primed with a disliked outgroup (gay men) showed evidence of interaction preparation (aggression) rather than direct stereotypic trait expression (passivity). In Study 2, participants with implicit positive attitudes toward the elderly walked more slowly after "elderly" priming, but participants with negative attitudes walked more quickly, results consistent with a preparatory account; the reverse was found priming "youth." Study 3 demonstrated that the accessibility of a primed category follows a pattern more consistent with that of goal-related constructs (including post-goal-fulfillment inhibition) than that of semantically primed constructs. Implications for the function of stored knowledge are discussed.     

Value from hedonic experience and engagement

Recognizing that value involves experiencing pleasure or pain is critical to understanding the psychology of value. But hedonic experience is not enough. I propose that it is also necessary to recognize that strength of engagement can contribute to experienced value through its contribution to the experience of motivational force--an experience of the intensity of the force of attraction to or repulsion from the value target. The subjective pleasure/pain properties of a value target influence strength of engagement, but factors separate from the hedonic properties of the value target also influence engagement strength and thus contribute to the experience of attraction or repulsion. These additional sources of engagement strength include opposition to interfering forces, overcoming personal resistance, using the right or proper means of goal pursuit, and regulatory fit between the orientation and manner of goal pursuit. Implications of the contribution of engagement strength to value are discussed for judgment and decision making, persuasion, and emotional experiences.     

The varying presuppositional nature of comparatives

The presuppositional nature of different types of comparatives was studied by obtaining subjects' judgments concerning the synonymity of pairs of comparative statements and the acceptability of single comparative statements. The results indicated that, in general, significantly greater presupposition was involved in the negative comparatives (e.g.,Bob is not as large as Fred) than in the positive comparatives (e.g.,Fred is larger than Bob), in the extreme comparatives (e.g.,Fred is more saintly than Bob) than in the regular comparatives (e.g.,Fred is better than Bob), in the ordinal comparatives (e.g.,Bob is more agile than Fred) than in the ratio comparatives (e.g.,Bob is heavier than Fred), and in the marked comparatives (e.g.,Bob is worse than Fred) than in the unmarked comparatives (e.g.,Fred is better than Bob). The results also indicated that comparative statements containing marked adjectives from a ratio scale can be interpreted neutrally. The implications of these results for the linguistic distinction between marked and unmarked adjectives are discussed. Presuppositions were found to apply equally to the subject and object terms of a comparative statement. In general, the results suggest that presuppositional effects are quite systematic and accumulative in nature.
