What types of reminiscence are associated with successful aging?

To resolve the controversy regarding the adaptive benefits of reminiscence, the study was conducted to investigate what types of reminiscence are associated with successful aging. On the basis of prior research and content analysis, 6 types of reminiscence were identified: integrative, instrumental, transmissive, narrative, escapist, and obsessive. Successful aging was operationally defined as higher than average ratings in mental and physical health and adjustment as determined by an interviewer and a panel of gerontological professionals. Reminiscence data were gathered from 88 men and women judged to be aging successfully and 83 men and women judged to be aging unsuccessfully. All subjects were between 65 and 95 years of age, with approximately half living in the community and half in institutions. As predicted, successful agers showed significantly more integrative and instrumental reminiscence but less obsessive reminiscence than their unsuccessful counterparts. Community dwellers also showed more instrumental and integrative reminiscence than institutionalized seniors showed. Thus, only certain types of reminiscence are beneficial.     

Is dream recall underestimated by retrospective measures and enhanced by keeping a logbook? An empirical investigation

In a recent review, Aspy, Delfabbro, and Proeve (2015) highlighted the tendency for retrospective measures of dream recall to yield substantially lower recall rates than logbook measures, a phenomenon they termed the retrospective-logbook disparity. One explanation for this phenomenon is that retrospective measures underestimate true dream recall. Another explanation is that keeping a logbook tends to enhance dream recall. The present study provides a thorough empirical investigation into the retrospective-logbook disparity using a range of retrospective and logbook measures and three different types of logbook. Retrospective-logbook disparities were correlated with a range of variables theoretically related to the retrospective underestimation effect, and retrospective-logbook disparities were greater among participants that reported improved dream recall during the logbook period. These findings indicate that dream recall is underestimated by retrospective measures and enhanced by keeping a logbook. Recommendations for the use of retrospective and logbook measures of dream recall are provided.     

What types of visual recognition tasks are mediated by the neural subsystem that subserves face recognition?

Three divided visual field experiments tested current hypotheses about the types of visual shape representation tasks that recruit the cognitive and neural mechanisms underlying face recognition. Experiment 1 found a right hemisphere advantage for subordinate but not basic-level face recognition. Experiment 2 found a right hemisphere advantage for basic but not superordinate-level animal recognition. Experiment 3 found that inverting animals eliminates the right hemisphere advantage for basic-level animal recognition. This pattern of results suggests that the cognitive and neural mechanisms underlying face recognition are recruited when computational demands of a shape representation task are best served through the use of coordinate (rather than categorical) spatial relations.     

What is learning? On the nature and merits of a functional definition of learning

Learning has been defined functionally as changes in behavior that result from experience or mechanistically as changes in the organism that result from experience. Both types of definitions are problematic. We define learning as ontogenetic adaptation—that is, as changes in the behavior of an organism that result from regularities in the environment of the organism. This functional definition not only solves the problems of other definitions, but also has important advantages for cognitive learning research.     

Who? What? When? Using a timeline technique to facilitate recall of a complex event

Accurately recalling a complex multi-actor incident presents witnesses with a cognitively demanding retrieval task. Given the important role played by temporal context in the retrieval process, the current research tests an innovative timeline technique to elicit information about multiple perpetrators and their actions. Adopting a standard mock witness paradigm, participants were required to provide an account of a witnessed event. In Experiment 1, the timeline technique facilitated the reporting of more correct details than a free recall, immediately and at a two-week retention interval, at no cost to accuracy. Accounts provided using the timeline technique included more correct information about perpetrator specific actions and fewer sequencing errors. Experiment 2 examined which mnemonic components of the timeline technique might account for these effects. The benefits of exploiting memory organization and reducing cognitive constraints on information flow are likely to underpin the apparent timeline advantage.     

Chunking during serial learning by a pigeon: III. What are the necessary conditions for establishing a chunk?

What are the minimal conditions for the formation of chunks by a pigeon learning an arbitrary list? Experiment 1 compared the acquisition of two types of chunkable list (each composed of colors and achromatic geometric forms): A----B----C----D'----E' (or A'----B'----C'----D----E) and A----B----C'----D'----E' (or A'----B'----C----D----E). The first type of list was acquired more rapidly than the second. On both lists, however, evidence of chunking did not emerge until the four-item phase of training (e.g., pauses at the end of one category of list item). In Experiment 2, chunking was shown to occur on four-item lists in which colors and forms were segregated (A----B----C'----D' and A'----B'----C----D), but not on lists in which the two types of items were interspersed (A----B'----C'----D and A'----B----C----D'). As in Experiment 1, evidence of chunking (pauses at chunk boundaries) did not appear until the fourth item was added.     

What is preexisting strength? Predicting free association probabilities,similarity ratings,and cued recall probabilities

Measuring lexical knowledge poses a challenge to the study of the influence of preexisting knowledge on the retrieval of new memories. Many tasks focus on word pairs, but words are embedded in associative networks, so how should preexisting pair strength be measured? It has been measured by free association, similarity ratings, and co-occurrence statistics. Researchers interpret free association response probabilities as unbiased estimates of forward cue-to-target strength. In Study 1, analyses of large free association and extralist cued recall databases indicate that this interpretation is incorrect. Competitor and backward strengths bias free association probabilities, and as with other recall tasks, preexisting strength is described by a ratio rule. In Study 2, associative similarity ratings are predicted by forward and backward, but not by competitor, strength. Preexisting strength is not a unitary construct, because its measurement varies with method. Furthermore, free association probabilities predict extralist cued recall better than do ratings and co-occurrence statistics. The measure that most closely matches the criterion task may provide the best estimate of the identity of preexisting strength.     

What types of advice do decision-makers prefer?

In the decision-making literature, “advice” has typically been defined very restrictively, as a recommendation concerning which alternative the decision-maker should choose. The present paper examines decision-makers’ reactions to this and three additional types of advice (a recommendation concerning which alternative not to choose, information about alternatives, and a recommendation concerning how to make the decision), along with another common form of interpersonal assistance (Social Support), from the perspective of maximizing decision accuracy and maintaining decision autonomy. The role of situational and individual differences is also examined. Results from two multilevel policy-capturing studies indicate that, although they consider recommendations regarding which alternative to choose to be important in some contexts, decision-makers often prefer to receive a type of advice that is greatly understudied by researchers—namely, the provision of information about alternatives. The implications of these findings for the study of advice-taking are discussed, as are future research directions.     

What are we frightened of?

I am concerned to understand that relation to a situation which we call fearing it. Some say this cannot be done: it is a brute fact about us that we fear certain things and we understand another's fear when we see that he confronts a situation of this sort (a basic fear object) or one which he understandably associates with this sort. In Section I, I argue that being associated with a basic fear object will not usefully explain a current fear. In Section II, I argue that the obvious candidates for being basic fears will not do the required work. The notion should be rejected. I then argue that to fear an object is to take it as exhibiting one's lack of control and I proceed to describe the nature and content of this notion.     

Is implicit learning perceptually inflexible? New evidence using a simple cued reaction-time task

Considerable research has been devoted to investigating learning without awareness. Burke and Roodenrys [Burke, D., & Roodenrys, S. (2000). Implicit learning in a simple cued reaction-time task. Learning and Motivation 31, 364–380] developed a simple learning task in which a cue shape predicts the arrival of a target shape (to which subjects respond) in a sequence of rapidly presented shapes, and found that all subjects responded faster to cued targets than to uncued targets, even those classified as unaware of the cue–target relationship. Two experiments were conducted to examine the perceptual flexibility of implicit (and explicit) learning using the paradigm developed by Burke and Roodenrys (2000). Perceptual flexibility was examined by altering the perceptual features of the cue shape. The results of the first experiment indicated the implicit, but not explicit, learning that occurs in this paradigm is perceptually inflexible. However, the second experiment indicated that perceptually flexible implicit learning can be encouraged by varying the nature of the experimental stimuli. These experiments therefore provide support for processing accounts of transfer.     

Pre-event discussion and recall of a novel event: how are children best prepared?

We investigated the conditions under which information 1 day before a novel event influenced 6-year-olds' recall 2 weeks later. In Experiment 1A, four preparation conditions included either the event goals, goals with narration of the event actions and objects, photographs of the objects with goals and narration, or photographs with narration and child verbalization of the actions and objects. Compared with an irrelevant preparation control condition, goals with narration reduced errors, but correct recall was increased only when photographs were included. Child verbalization together with goals, narration, and photographs increased correct recall relative to goals with narration. In Experiment 1B, neither photographs nor preparation alone improved recall relative to the control condition. Experiment 2 found no further advantage of increasing children's participation in the preparation via questions. Overall, the impact of preevent information on memory is influenced by the nature of the information and the child's participation in the preparation.     

What are you hiding? Initial validation of the reaction time-based searching concealed information test

The reaction time-based concealed information test (RT-CIT) has been used to judge the veracity of an examinees claim to be naïve by using RTs to test for recognition of relevant details. Here, we explore the validity of the RT-CIT to generate new knowledge about the incident—the searching CIT. In a mock terrorism study (n = 60) the RT-CIT not only allowed to link suspects to known crime details, but also allowed to reveal new crime details well above chance. A simulation study confirms the potential of the searching RT-CIT and identifies conditions under which it performs best. We used an archival dataset that met these conditions (high CIT effect, large number of item repetitions), and found better item classification performance than in the mock terrorism study. The searching RT-CIT could be a new, promising investigative tool to reveal new (e.g., crime) details to the investigative party.     

What are the phenomena of physics?

Depending on different positions in the debate on scientific realism, there are various accounts of the phenomena of physics. For scientific realists like Bogen and Woodward, phenomena are matters of fact in nature, i.e., the effects explained and predicted by physical theories. For empiricists like van Fraassen, the phenomena of physics are the appearances observed or perceived by sensory experience. Constructivists, however, regard the phenomena of physics as artificial structures generated by experimental and mathematical methods. My paper investigates the historical background of these different meanings of “phenomenon” in the traditions of physics and philosophy. In particular, I discuss Newton’s account of the phenomena and Bohr’s view of quantum phenomena, their relation to the philosophical discussion, and to data and evidence in current particle physics and quantum optics.     

What are the prospects for a higher-order stimulus theory of perception?

Abstract.— Gibson has advocated a pure higher-order stimulus theory of perception. Johansson has agreed that the stimuli for perception are higher order variables of stimulation. However, unlike Gibson, Johansson assigns an important role to decoding principles in determining perception. Evidence is reviewed to show that percept-percept relations are involved in perception. On this ground it was argued that the prospects for a successful pure-stimulus theory are poor and that Johansson's views should be elaborated to include various types of decoding principles.     

What are groups?

In this paper I argue for a view of groups, things like teams, committees, clubs and courts. I begin by examining features all groups seem to share. I formulate a list of six features of groups that serve as criteria any adequate theory of groups must capture. Next, I examine four of the most prominent views of groups currently on offer—that groups are non-singular pluralities, fusions, aggregates and sets. I argue that each fails to capture one or more of the criteria. Last, I develop a view of groups as realizations of structures. The view has two components. First, groups are entities with structure. Second, since groups are concreta, they exist only when a group structure is realized. A structure is realized when each of its functionally defined nodes or places are occupied. I show how such a view captures the six criteria for groups, which no other view of groups adequately does, while offering a substantive answer to the question, “What are groups?”
