<dim:field mdschema="dc" element="description" qualifier="abstract" lang="en">n this experiment positive reinforcement was used to teach horses to select photos of either angry (n=2) or happy (n=2) human facial expressions as opposed to a neutral expression of the same individual. At the end of the experiment, two horses were operating at an accuracy level significantly above chance: one from the group assigned to angry faces (χ2 = 25, p&lt;.001) and one from the group assigned to happy faces (χ2 = 7.84, p=.005). However the other horses from both angry face (χ2 = 0.16, p= 0.689) and happy face (χ2 = 0, p=1) groups did not exceed chance levels and they were considered to have not learned the task. A finding that even one horse operates significantly above chance indicates that the cognitive skill is within the capacity of the species. Therefore, it is suggested that horses can discriminate between neutral human facial expressions and facial expressions of emotion. However, as only a few horses reached discrimination, alongside the length of time it took, demonstrates that horses are likely not highly sensitive to differences in facial expression. More research is needed to either support or refute this finding. However, if the finding stands, the result raises interesting questions concerning the mechanics of this differentiation, including whether this ability is innate or learned. It further carries practical importance for horse welfare and management.</dim:field>
<dim:field mdschema="dc" element="description" qualifier="abstract" lang="is">Í þessari rannsókn var jákvæð styrking notuð til þess að kenna hestunum að velja myndir af annað hvort reiðum (n=2) eða glaðlegum (n=2) svipbrigðum í staðinn fyrir hlutlaus svipbrigði sömu manneskju. Í lok rannsóknarinnar völdu tveir hestar rétta mynd yfir marktæknimörkum: einn úr hópnum valdi oftar reiðan svip (χ2 = 25, p&lt;.001) og einn úr hópnum ánægðan svip (χ2 = 7.84, p=.005). Hinir hestarnir völdu bæði reiðan svip (χ2 = 0.16, p= 0.689) og ánægðan svipur (χ2 = 0, p=1), voru ekki yfir marktæknimörkum og töldust ekki vera búnir að læra verkefnið. Uppgötvunin um að einum hesti hafi tekist að vinna yfir marktæknimörkum gefur til kynna að vitsmunalegir hæfileikar hans geti þýtt að tegundin geti það líka. Þar af leiðandi er ályktað að hestar geti gert upp á milli hlutlausra svipbrigða og tilfinningalegra svipbrigða hjá manneskjum. Þrátt fyrir það tókst aðeins fáum einstaklingum að læra að gera upp á milli svipbrigðanna og eins hve langan tíma það tók að kenna þeim það, sýnir fram á að hestar eru ekki mjög næmir fyrir mismunandi svipbrigðum hjá fólki. Fleiri rannsókna er þörf til að styðja eða hrekja staðhæfinguna. Ef ályktunin stenst vekur hún upp áhugaverðar spurningar varðandi það hvort þessi eiginleiki að greina á milli svipbrigða sé eðlislægur eða lærður. Sú vitneskja er líka verulega mikilvægt fyrir notkun og velferð hrossanna.</dim:field>
