Virtual HR: The impact of information technology on the human resource professional

Accelerated investment and innovation in information technology (IT) offers prospects for conducting business in ways that are radically different from the past. Despite the growing presence of IT within organizations, however, we do not have a clear understanding of how IT impacts the role of professionals. We address this issue by investigating how jobs in one professional occupational segment, human resources (HR) professionals are influenced by extensive use of IT within the human resource department. Specifically, we examine how HR professionals handle HR information as well as the expectations placed on them resulting from an increased reliance on IT. Our findings suggest that IT enables HR professionals to more efficiently access and disseminate information while it also influences what is expected of them. Implications and future directions are discussed.     

Not all happy people are lazy or stupid: Evidence of systematic processing in happy moods

Two experiments investigated the effects of mood on the use of global trait information in impression formation tasks. Participants in both experiments formed an impression of a target based on traits and a series of behaviors that were both consistent and inconsistent with the traits. In Experiment 1, participants in happy moods, relative to those in unhappy moods, made impression judgments that reflected the evaluative implications of the trait information to a greater extent than the behaviors, regardless of the order in which they received the information. In Experiment 2, both happy and sad participants engaged in systematic processing, as reflected by the recall data, but only happy participants’ recall of target information was significantly biased by the global trait information they received. These findings are consistent with the affect-as-information model in which affective cues influence the extent to which individuals rely on general knowledge and, importantly, are inconsistent with models that posit that happiness results in reduced motivation or ability to process information carefully.     

A social validation explanation for mutual enhancement

Group members experience mutual enhancement when they evaluate one another’s task capabilities more positively because they are discussing shared as compared to unshared information. Two experiments investigated a social validation explanation for mutual enhancement. In Experiment 1, members of dyads read and discussed either shared or unshared information and collectively recalled this information under conditions where accuracy was important or not. Mutual enhancement occurred when need for accuracy was higher, but not when it was lower. In Experiment 2, members of dyads read validating or non-validating information from an outsider after they collectively recalled shared or unshared information. Members who discussed unshared information and received no validating communication from the outsider gave one another the lowest task capability ratings compared to members who discussed shared information and/or received validating communication from the outsider. All of these results are consistent with a social validation explanation for mutual enhancement.     

What is it for a Life to go Well (or Badly)?: Some Critical Comments on Wayne Sumner’s Theory of Welfare

In an effort to construct a plausible theory of experience-based welfare, Wayne Sumner imposes two requirements on the relevant kind of experience: the information requirement and the autonomy requirement. I argue that both requirements are problematic. First, I argue (very briefly) that a well-know case like ‘the deceived businessman’ need not support the information requirement as Sumner believes. Second, I introduce a case designed to cast further doubt on the information requirement. Third, I attend to a shortcoming in Sumner’s theory of welfare, namely that it is unclear which of later and informed assessments are to be treated as authoritative when it comes to the evaluation of a person’s welfare. Finally, I suggest that, in combination with ‘welfarism’ (to which Sumner subscribes, and which has it that welfare is all that matters from a moral viewpoint), the information requirement entail morally troublesome conclusions: e.g. the conclusion that, from a moral point of view, we should, other things being equal, only to be concerned with the alternative that makes one person slightly better off in respect of welfare instead of also being morally concerned with the alternative that makes one person very happy.     

When vaccinating against information reduction works and when it does not work

Practice not only affects how information is processed, but also which information is processed. The Information-Reduction Hypothesis (i.e. Haider & Frensch, 1996) holds that — with practice — irrelevant task information (i.e. information that is not logically needed to correctly perform the task) is discarded from processing. Recently, Gaschler and Frensch (2007) have demonstrated that Information Reduction is not affected by the frequency with which individual task configurations are presented: well-practiced and little-practiced irrelevant task configurations are discarded at the same point in time during practice; Information Reduction is thus an item-general phenomenon. These findings suggest that Information Reduction is at least in part a consequence of top-down, voluntary control. In the present research, we ask how tasks can be constructed such that Information Reduction is avoided. Our results show that item-general Information Reduction is observed even when it leads to severe processing costs (i.e. errors). On the whole, the present results are in line with models of skill acquisition incorporating top-down modulation (e.g. Haider & Frensch, 2002) and are incompatible with purely data-driven accounts of skill acquisition (e.g. Logan, 1988; Nosofski & Palmeri, 1997; Palmeri, 1997; Rickard, 2004).     

Psychological Warfare in Vietnam

Although psychological warfare was practiced to a greater degree in the Vietnam conflict than in any other war in history, virtually nothing has been published about it. Perhaps few wished to be identified with such activity, or it may be that security considerations prevented discussion of the operations. At any rate, the end of the Cold War has made it possible to take a brief look at a hitherto unknown (or undiscussed) subject. This article, however, does not make a pretense of being comprehensive for the whole war, but rather reflects personal observations during one brief period of intense fighting—the summer of 1966.     

Acquisition of cognitive compiling

Language involves both structure and process. Giving each its due, we present a cognitive process model and show how its empirical success is related to claims about syntactic structure. Innate constraints on syntax are a central issue in linguistic theory, so it is a matter of concern that a widely accepted view of phrase structure constraints (X-bar theory) appears to be violated in some recent comprehension experiments with children. However, what is directly observed in the experiments is not a syntactic structure but the execution of a plan. We present a language of process for representing such plans and thereby provide a unified explanation of several developmental phenomena, including the results of the above experiments and of new experiments suggested by our approach. The explanation is in terms of the cognitive resources required to formulate and execute a plan. Since the explanation is based on nonsyntactic processing, the children's syntax need no longer be held faulty. This conclusion invigorates the claim that the range of phrase structures available to children is biologically constrained.     

Students' perceptions of personality needs and environmental press as a function of program separation

A sample of 1,877 high school seniors completed the Activities Index and High School Characteristics Index. The student responses were used to identify personality needs and environmental press differences across program and degree of program separation variables.It was concluded that: (1) College preparatory students perceived high personality needs for intellectual endeavors, while vocational students had needs for the tangible and concrete. (2) The personality differences across degrees of program separation suggested the physical proximity of the two program groups affected students' interpersonal relationships. (3) Several of the environmental press were exactly opposite the students' perceived personality needs. (4) The nonsignificant needs-press relationships suggested that high school environments were not facilitating the personality needs of students. (5) Comprehensive high schools seemed the most viable administrative configuration for servicing the diverse needs of today's high school students.     

Uncertainty about the rest of the sentence

A word-by-word human sentence processing complexity metric is presented. This metric formalizes the intuition that comprehenders have more trouble on words contributing larger amounts of information about the syntactic structure of the sentence as a whole. The formalization is in terms of the conditional entropy of grammatical continuations, given the words that have been heard so far. To calculate the predictions of this metric, Wilson and Carroll's (1954) original entropy reduction idea is extended to infinite languages. This is demonstrated with a mildly context-sensitive language that includes relative clauses formed on a variety of grammatical relations across the Accessibility Hierarchy of Keenan and Comrie (1977). Predictions are derived that correlate significantly with repetition accuracy results obtained in a sentence-memory experiment (Keenan & Hawkins, 1987).     

Suboptimal tradeoffs in information seeking

Explicit information-seeking actions are needed to evaluate alternative actions in problem-solving tasks. Information-seeking costs are often traded off against the utility of information. We present three experiments that show how subjects adapt to the cost and information structures of environments in a map-navigation task. We found that subjects often stabilize at suboptimal levels of performance. A Bayesian satisficing model (BSM) is proposed and implemented in the ACT-R architecture to predict information-seeking behavior. The BSM uses a local decision rule and a global Bayesian learning mechanism to decide when to stop seeking information. The model matched the human data well, suggesting that adaptation to cost and information structures can be achieved by a simple local decision rule. The local decision rule, however, often limits exploration of the environment and leads to suboptimal performance. We propose that suboptimal performance is an emergent property of the dynamic interactions between cognition and the environment.
