Consciousness of the self (COS) and explicit knowledge

Starting with distinction between explicit and implicit knowledge and the traditional philosophical distinction between COS (the consciousness of self) as an object and COS as a subject, we suggest a triple classification of COS experience into three modes, each corresponding to a different state of consciousness. When one acts automatically COS is totally embedded within the representation of the environment. When one monitors or attends to one's experience, the self is implied by an explicit representation of one's attitudes, consistent with Descartes' cogito insight 'I think therefore I am' (1641,1984). However, a reflexive thought, e.g., 'I know fact x,' requires an explicit representation of the self. This analysis highlights the existence of an intermediate mode of COS as a subject and suggests its possible connection to monitoring one's behavior.     

Selective attention fails to alter the dichotic listening lag effect: evidence that the lag effect is preattentional

Berlin et al. (1973) reported that either stimulus from a dichotic pair of consonant-vowel syllables is processed preferentially when its presentation is delayed by 30-60 ms. In the first of three experiments with 60 normal right-handed adults, we replicated the Berlin et al. "lag effect," but only for asynchronies between 60 and 90 ms. In Experiment 2 subjects focused attention selectively on one ear. The results indicated that focused attention and stimulus asynchrony have additive effects: Performance improved at the attended ear irrespective of stimulus asynchrony, but the lag effect remained unchanged relative to the divided-attention condition. Experiment 3 entailed a signal detection task that allowed separate analysis of detection and localization accuracy. As in previous studies, selective attention to one ear increased the accuracy of localization but not detection at the attended ear. Both dependent measures indicated a lag effect that remained invariant as attention was manipulated. These findings imply that the lag effect is attributable to a preattentional stage of auditory processing.     

Motivation modulates the effect of approach on implicit preferences

With three studies, we investigated whether motivational states can modulate the formation of implicit preferences. In Study 1, participants played a video game in which they repeatedly approached one of two similar beverages, while disregarding the other. A subsequent implicit preference for the target beverage emerged, which increased with participants’ thirst. In Study 2, participants approached one brand of potato chips while avoiding the other: Conceptually replicating the moderation observed in Study 1, the implicit preference for the approached brand increased with the number of hours from last food intake. In Study 3, we experimentally manipulated hunger, and the moderation effect emerged again, with hungry participants displaying a higher implicit preference for the approached brand, as compared to satiated participants. In the three studies, the moderation effect was not paralleled in explicit preferences although the latter were affected by the preference inducing manipulation. Theoretical implications and open questions are discussed.     

Correcting the oral reading errors of a beginning reader

Correcting student errors is an important educational concern for teachers. In this study, an alternating treatments design was used to compare the effectiveness of four methods for correcting oral reading errors, including immediate word supply, delayed word supply, sound out (phonics analysis), and directed rehearsal techniques. The subject was a 6-year-old beginning reader with average ability. Results showed that the directed rehearsal procedure was the most effective method. This study demonstrated that teachers can use rigorous research methods in their own classrooms to determine which teaching strategies they should use with their students.     

Time perception: Effects of sex and sound intensity on scales of subjective duration

Six women and six men reproduced ten time intervals varying in logarithmic steps between 1.3 and 20 s. The durations were indicated by white noise of 10, 25, 40 and 55 dB SL, different sound intensities in different sessions. It was found that (i) greater sound intensity entails shorter reproductions, and (ii) reproductions by male observers are shorter than those by female, although for both (i) and (ii) there is an interaction with the standard durations. The data were treated in accordance with the "parallel-clock model" (Eisler, 1975), whereby the parameters of the psychophysical power function are determined from duration reproduction data. As in previous experiments (Eisler, 1975), the data showed a break in the function entailing two segments. The effect of sound intensity could be attributed to the exponent, which was lower for stronger noise, and the effect of sex to the weight coefficient of the upper relative to the lower segment of the psychophysical function, the coefficient being lower for men.     

Multitrait Multimethod validation of Implicit Association Test as a measure of individual differences in personality: Is there personality at all?

The objective of the study was to investigate the validity of IAT in the assessment of the Big five personality traits. We employed the Multi-Trait Multi-Method (MTMM) approach on a sample of 146 respondents. We collected measures on IATs assessing Big five personality traits, self-reports, and two ratings of close others of different gender on NEO PI-R. Additionally, we assessed behavior related to the Big five personality traits in a structured interview where three experts independently provided rating measures. MTMM analyses suggest that personality IAT measures have little in common with personality traits measured traditionally using explicit methods. The evidence does not support the claim that personality IAT can serve as a valid measure of individual differences in personality traits.     

Two Models of Moral Judgment

This paper compares two theories and their two corresponding computational models of human moral judgment. In order to better address psychological realism and generality of theories of moral judgment, more detailed and more psychologically nuanced models are needed. In particular, a motivationally based theory of moral judgment (and its corresponding computational model) is developed in this paper that provides a more accurate account of human moral judgment than an existing emotion‐reason conflict theory. Simulations based on the theory capture and explain a range of relevant human data. They account not only for the original data that were used to support the emotion – reason conflict theory, but also for a wider range of data and phenomena.     

A high implicit affiliation motive does not always make you happy: A corresponding explicit motive and corresponding behavior are further needed

Satisfaction of the implicit affiliation motive is known to be positively related to emotional well-being, whereas the frustration of the implicit affiliation motive leads to impairment of well-being. In the present research we specified two conditions that are responsible for the satisfaction and frustration of the implicit motive. Referring to research on the congruence of implicit and explicit motives, we assumed that a corresponding explicit affiliation motive leads to satisfaction of the implicit motive. Corresponding affiliation behavior constitutes the second condition. Three studies confirmed the hypothesis that both conditions must be fulfilled in order to positively connect the implicit affiliation motive to emotional well-being. Participants with high implicit and explicit affiliation motives and who additionally showed a large amount of affiliation behavior reported the lowest negative affectivity and the highest life satisfaction compared to participants who lacked one of the conditions.

Which children benefit from letter names in learning letter sounds?

Typical U.S. children use their knowledge of letters' names to help learn the letters' sounds. They perform better on letter sound tests with letters that have their sounds at the beginnings of their names, such as v, than with letters that have their sounds at the ends of their names, such as m, and letters that do not have their sounds in their names, such as h. We found this same pattern among children with speech sound disorders, children with language impairments as well as speech sound disorders, and children who later developed serious reading problems. Even children who scored at chance on rhyming and sound matching tasks performed better on the letter sound task with letters such as v than with letters such as m and h. Our results suggest that a wide range of children use the names of letters to help learn the sounds and that phonological awareness, as conventionally measured, is not required in order to do so.
