Detection of Fs in a single statement: The role of phonetic recoding

Most college-student readers have difficulty in detecting the letter F in instances of the word OF embedded in a single statement. Throughout a series of five experiments designed to clarify the basis of these detection failures, their unique and robust nature was demonstrated. The detection failures persisted in spite of repeated attempts to detect the letters by subjects who, in separate conditions and experiments, first memorized or copied the statement, or who, for purposes of comparison, also detected the O in OF, the N in ON, or the F in IF, or who read the statement in a number of physical formats, which included lower and upper letter cases, scrambled syntax, unsegmented letter strings, and vertical (list) presentation. Although many of these manipulations significantly improved performance, none produced perfect performance or performance comparable to the detection of F in IF. Several hypotheses, including those of redundancy, unitization, and phonetic recoding, were tested as explanations of the detection failures: The hypothesis that received the strongest support was that of phonetic recoding. This hypothesis focuses upon the atypical pronunciation of F as/v/(as in the word OF), rather than as the more typical/f/. In short, this reading illusion was concluded to be, in large part, a result of the subjects’ scanning their acoustic rather than their visual images of the printed word.     

Derivatives of the Self-Directed Search: Potential clinical and evaluative uses

Four derivatives of the Self-Directed Search (SDS), accuracy in estimating one's profile, differentiation of one's six SDS personality types, consistency of the types within one's summary code, and congruence of the summary code with the preferred occupational area, were computed and correlated with other indices of career maturity for 138 community college students. Accuracy in estimating one's SDS profile correlated significantly with five other career maturity indices, but the other derivatives tended not to relate to the other career maturity criteria. The discussion examines the implications of using the Accuracy derivative to identify clients in need of assistance with career development and to unobtrusively evaluate career development interventions, and it suggests ways of increasing the reliability of the derivatives and promising directions for further research.

Random error in additive decompositions of multiattribute utility

Decomposition is a common strategy for dealing with the complexity of multiattribute decision problems. A cognitively demanding task is broken down into tasks requiring simpler, perhaps easier, judgments which can then be aggregated. But individual judgments can be inconsistent in systematic or random fashion and when aggregated there is the possibility of propagation of this inconsistency. In this paper inconsistency in the form of random error is investigated in the context of additive decomposition of multiattribute utility. The process of aggregation of random error is studied and a comparison made with random error in holistic estimates of multiattribute utility. Conditions under which decomposition improves the consistency of the multiattribute utility estimate are presented and discussed.     

Chunking, rule learning, and multiple item memory in rat interleaved serial pattern learning

Nonhuman animals, like humans, appear sensitive to the structure of the elements of sequences, perhaps even when the structure relates nonadjacent elements. In the present study, we examined the contribution of chunking, rule learning, and item memory when rats learned serial patterns composed of two interleaved subpatterns. In one group, the first interleaved subpattern was a formally simple sequence, whereas in two other groups the first subpattern was formally more complex, containing 2 or 4 violation elements, respectively. In all groups, the second interleaved subpattern encountered was formally simple. Evidence from the study suggests that rats chunked their interleaved patterns into component subpatterns, that is, they cognitively sorted pattern elements to form chunks based on nonadjacent structural relationships that can be characterized as rules. They also learned interitem associations via traditional discrimination learning to use adjacent elements as compound or configural cues for later events in the sequence. Thus, the evidence suggests that rats used chunking, rule learning, and interitem association learning concurrently to master these complex patterns.     

Effects of divided attention and word concreteness on correct recall and false memory reports

Lists of thematically related words were presented to participants with or without a concurrent task. In Experiments 1 and 2, respectively, English or Spanish word lists were either low or high in concreteness (concrete vs abstract words) and were presented, respectively, auditorily or visually for study. The addition of a concurrent visual or auditory task, respectively, substantially reduced correct recall and doubled the frequency of false memory reports (nonstudied critical or theme words). Divided attention was interpreted as having reduced the opportunity for participants to monitor successfully their elicitations of critical associates. Comparisons of concrete and abstract lists revealed significantly more recalls of false memories for abstract than concrete word lists. Comparisons between two levels of attention, two levels of word concreteness, and two presentation modalities failed to support the "more is less" effect by which enhanced correct recall is accompanied by increased frequencies of false memories.     

Leader Positivity and Follower Creativity: An Experimental Analysis

Using an experimental research design, 191 working adults were randomly assigned to two experimental conditions in order to test a theoretical model linking leader and follower positive psychological capital (PsyCap). Multiple methods were used to gather information from the participants. We found when leader PsyCap was manipulated experimentally, it was positively related to follower PsyCap. Subsequently, follower PsyCap was significantly related to employee's originality of ideas; one important component of creativity in the workplace. We discuss the theoretical contributions of linking leader and follower PsyCap in what emerges as a directional contagion effect, and the mediating role of follower PsyCap in enhancing follower creative task performance. Further, employee selection and development as well as leadership development practical implications are discussed. We conclude with a discussion of limitations and future research directions.

Where,O death,is thy sting? The meaning-providing function of beliefs in literal immortality

Terror management theory suggests that humans invest in cultural worldviews that allay mortality-related anxiety by promising death transcendence. Many religious individuals adhere to belief in literal immortality – believing that one will live on after death. Across two studies (n?=?1137), we explored the terror management function of such beliefs by exploring whether these beliefs are associated with lower death anxiety and greater meaning among individuals of varying religiousness. In both Study 1 (n?=?236) and Study 2 (n?=?901), belief in literal immortality was related to lower death anxiety only among intrinsically religious participants. Moreover, meaning in life mediated the relationship between belief in literal immortality and death anxiety. Study 2 clarified that this mediational relationship was only present for intrinsically religious individuals. We discuss the importance of particular religious beliefs in the provision of meaning in order to manage existential concerns.
