The question whether memory aberrations in posttraumatic stress disorder (PTSD) also manifest as an increased production of false memories is important for both theoretical and practical reasons, but is yet unsolved. Therefore, for the present study we investigated veridical and false recognition in PTSD with a new scenic variant of the Deese-Roediger-McDermott (DRM) paradigm, which was administered to traumatized individuals with PTSD (n=32), traumatized individuals without PTSD (n=30), and non-traumatized controls (n=30). The PTSD group neither produced higher rates of false memories nor expressed more confidence in errors, but did show inferior memory sensitivity. Whereas depressive symptoms did not correlate with veridical nor false recognition, state dissociation was positively associated with false memories. 相似文献

Co‐production has been traditionally studied in the context of industrial and service markets. This study investigates the consumer's search for meaning and fulfillment via one type of co‐production, collective co‐production. The case study method was utilized to examine knife making from kits. The findings unpack a three‐part co‐production process (design, production, and consumption) that results in significant identity ramifications for consumers. During the design stage of knife making, the informants shaped their self‐concept through social inspiration, creative self‐expression, and identification with the primal sense of self. The production stage provided internal validation of the self‐concept through a pseudochallenge that was achieved through learning activities. The consumption stage provided external validation of the self‐concept as the informants shared their co‐production experience with others. Theoretical implications are discussed.

This study explored the basis of self-sacrificial prosocial behavior in small groups. Seventy-eight undergraduates (39M, 39F) filled out a thirty-item personality scale and then participated in a "group problem-solving study" in which the monetary success of a three-person group depended upon one of its members volunteering to endure pain (a cold stressor test) and inconvenience (being soaked in a dunk tank). There were 13 groups consisting of two females and one male, and 13 groups consisting of two males and one female. Across groups, the behavior of the altruist was judged to be more costly, challenging, and important and he/she was liked better, rewarded with more money, and preferred as a future experimental partner. Groups containing two males showed more evidence of competition to become altruists than groups containing two females, and personality traits were more effective predictors of altruistic behavior in males than in females. We conclude that competition between males and "showing off" are key factors in triggering self-sacrificial altruistic behavior. 相似文献

Theistic and spiritually based beliefs and behaviors have been demonstrated to consistently predict physical and mental health, although the psychological processes underlying these relationships are unclear. This study investigated associative relationships and pathways of mediation between religious functioning, locus of control (LOC) and health. The sample consisted of 122 Christians (79 women, 43 men) who were predominately Catholic, ranging in age from 18 to 80 (M = 45.47, SD = 15.0). Participants were recruited from churches in the Western suburbs of Melbourne, Australia, and completed a questionnaire package measuring (1) psychological and physical health, (2) the religious variables of awareness of God, instability and impression management, and (3) God, internal and external LOC domains. Results indicated that awareness of God and internal LOC were associated with better health, whereas external LOC and instability were associated with poorer health. God LOC and impression management were not significantly associated with health. Sobel tests were used to analyse mediation hypotheses. Internal LOC was found to mediate the relationship between awareness of God and better psychological health, and external LOC was found to mediate the relationship between instability and poorer psychological health. These findings are of considerable clinical significance. 相似文献

We examined the developmental sequence of letter name knowledge acquisition by children from 2 to five years of age. Data from 2 samples representing diverse regions, ethnicity, and socioeconomic backgrounds (ns = 1074 and 500) were analyzed using item response theory (IRT) and differential item functioning techniques. Results from factor analyses indicated that letter name knowledge represented a unidimensional skill; IRT results yielded significant differences between letters in both difficulty and discrimination. Results also indicated an approximate developmental sequence in letter name learning for the simplest and most challenging to learn letters--but with no clear sequence between these extremes. Findings also suggested that children were most likely to first learn their first initial. We discuss implications for assessment and instruction. 相似文献

The present study examined the impact of divided attention on children's and adults' neutral and negative true and false memories in a standard Deese/Roediger-McDermott paradigm. Children (7- and 11-year-olds; n = 126) and adults (n = 52) received 5 neutral and 5 negative Deese/Roediger-McDermott word lists; half of each group also received a divided attention task. The results showed that divided attention affected children's and adults' false memory levels differently but did not alter true memory differently. Our results revealed a developmental shift in that divided attention lowered children's false memory rates but increased adults' false memory rates, regardless of the nature of the material (i.e., neutral or negative). Our study indicates that manipulations that target conscious processing (e.g., divided attention) result in marked qualitative and quantitative differences between children's and adults' false memories but not true memories. 相似文献

Research has demonstrated that implicit and explicit evaluations of the same object can diverge. Explanations of such dissociations frequently appeal to dual-process theories, such that implicit evaluations are assumed to reflect object-valence contingencies independent of their perceived validity, whereas explicit evaluations reflect the perceived validity of object-valence contingencies. Although there is evidence supporting these assumptions, it remains unclear if dissociations can arise in situations in which object-valence contingencies are judged to be true or false during the learning of these contingencies. Challenging dual-process accounts that propose a simultaneous operation of two parallel learning mechanisms, results from three experiments showed that the perceived validity of evaluative information about social targets qualified both explicit and implicit evaluations when validity information was available immediately after the encoding of the valence information; however, delaying the presentation of validity information reduced its qualifying impact for implicit, but not explicit, evaluations. 相似文献
