How Can Decision Making Be Improved?

ABSTRACT— The optimal moment to address the question of how to improve human decision making has arrived. Thanks to 50 years of research by judgment and decision-making scholars, psychologists have developed a detailed picture of the ways in which human judgment is bounded. This article argues that the time has come to focus attention on the search for strategies that will improve bounded judgment because decision-making errors are costly and are growing more costly, decision makers are receptive, and academic insights are sure to follow from research on improvement. In addition to calling for research on improvement strategies, this article organizes the existing literature pertaining to improvement strategies and highlights promising directions for future research.     

How Masculine Ought I Be? Men's Masculinity and Aggression

Male undergraduates completed the Bem Sex RoleInventory (BSRI) as they are (actual), as others thoughtthey should be (ought), as they thought they should beideally (ideal), and then rated the importance of each item. Discrepancy scores were derivedby subtracting actual from either ought (oughtdiscrepancy) or from ideal (ideal discrepancy) andweighting scores by the importance of each item. BSRImasculine items provided the basis for masculinitydiscrepancies, and filler items, for generaldiscrepancies. With only two or three exceptions,participants were Caucasian. Each man competed againsta bogus competitor on a computer version of the Taylorreaction-time aggression paradigm that yielded a measureof both overt (intensity of the noise blast putativelydelivered to the opponent) and covert (noise blastduration) aggression. Men with high masculine"ought" discrepancies engaged in morecovert-and not more overt — aggression than didlows, an effect not moderated by provocation level.Those with high masculinity scores were more overtly aggressive than werelow masculinity men.     

Failure to find a syllabic effect in number naming

Experiment I replicated the number-naming studies of Eriksen, Pollack, and Montague (1970) and Klapp (1971) but failed to find consistent evidence of a syllabic effect in naming latencies. Experiment II employed a different set of numbers to investigate sources of confounding in the original stimuli. Again, no syllabic effect was obtained. Both studies provided some evidence that the decades are processed faster.     

Parallel but temporally displaced visual half-field metacontrast functions

Using a classic letter-ring metacontrast paradigm, left and right visual field meta-contrast functions were separately determined. The parallel U-shaped recognition functions for both half-fields were found to interact differentially with stimulus onset asynchrony, the left visual field function being displaced by 13 ms toward longer test stimulus-masking stimulus separations. This result was consistent with the hypothesis of longer processing time requirements for verbal stimuli delivered to the right than to the left hemisphere. This indicates that the neural locus (loci) responsible for left visual field verbal processing delay is (are) capable of mediating metacontrast phenomena. It was tentatively concluded that a relative processing delay within the right hemisphere underlies the differing visual half-field metacontrast interaction with stimulus onset asynchrony.     

Mental size scaling examined

Observers made same-different shape judgments of stimuli that were identical in shape and size different in shape but not in size, or differed in relative size along a number of steps for both same- and different- shaped forms. "Same" judgment RTs increased monotonically with increases in the magnitude of the relative size difference. In contrast, "different" judgment RTs were unaffected by changes in relative size. A second experiment in which stimulus presentation was successive rather than simultaneous yielded essentially the same results. Consideration was given to a dual- process model in which a time-consuming analog process normalizes stimuli that are size discrepant prior to a comparison stage that is operative for those structures responsible for "same" decisions but not for "different" judgments. Some evidence that seems inconsistent with a normalization process which operates prior to contact with memory was discussed, and an alternative explanation in which the early detection of a size difference causes changes in decision criteria was suggested.     

Phonological encoding in the lexical decision task

In lexical decision experiments, subjects have difficulty in responding NO to non-words which are pronounced exactly like English words (e.g. BRANE). This does not necessarily imply that access to a lexical entry ever occurs via a phonological recoding of a visually-presented word. The phonological recoding procedure might be so slow that when the letter string presented is a word, access to its lexical entry via a visual representation is always achieved before phonological recoding is completed. If prelexical phonological recodings are produced by using grapheme-phoneme correspondence rules, such recodings can only occur for words which conform to these rules (regular words), since applications of the rules to words which do not conform to the rules (exception words) produce incorrect phonological representations. In two experiments, it was found that time to achieve lexical access (as measured by YES latency in a lexical decision task) was equivalent for regular words and exception words. It was concluded that access to lexical entries in lexical decision experiments of this sort does not proceed by sometimes or always phonologically recoding visually-presented words.
